Doorway is a program which allows almost any program to be run as a door and bestows the ability to remotely control a computer over a modem. Bulletin boards can utilize DOORWAY to transform normal programs into "DOORS", and anyone can use DOORWAY as a remote utility. As a remote utility, DOORWAY will allow you to control a distant computer via modem, as if you were there. This has many benefits over CTTY, as will be discussed later. DOORWAY will redirect all programs on the host, with the one exception of programs which use bit-mapped graphics. DOORWAY is NOT a CTTY function. DOORWAY does a shell to the program to run, or shells COMMAND.COM, when used as a remote utility. It then translates and redirects all video to the required COM port and all COM port inputs to the keyboard buffer. BIOS interrupts or screen RAM comparisons are used, so that programs, which DOS CTTY cannot redirect, can still be used. The Board's keyboard is active so that the SYSOP (or person on the HOST end) can aid a remote user, and the SYSOP can see what the user is doing. COMMAND.COM is not loaded by DOORWAY unless specifically instructed to do so by the HOST setup; therefore, a user cannot break a program and get to DOS. If the user exits or breaks the program, he will simply return to DOORWAY, which will return to the board after resetting all vectors, including any the application program may have changed. Doorway monitors Carrier Detect, and after displaying a message that carrier was lost, returns to the board. It also monitors the input character string and traps any character(s) the SYSOP wants trapped (such as ^C). It will also abort a program with any character(s) the SYSOP has defined, thus making it possible to run UNBREAKABLE programs, such as many commercial games. The keyboard time and user's time are monitored, and if either expires, DOORWAY will return to the board. The users's time will be what is computed as being left when PCBOARD.SYS or DOOR.SYS is read, unless overridden by a command line switch. Keyboard expiration time is changeable, but defaults to 255 seconds (4 minutes 15 seconds). The keyboard timeout is measured on both the com port and the board's keyboard, so characters entered at either will reset the timer. The keyboard timer can also be reset by the video going out, if desired. Full ANSI GRAPHICS are supported, but if your program doesn't need it, DOORWAY will work just fine in NON-ANSI mode. DOORWAY also allows you to send all the extended keyboard codes, such as the cursor keys and Function keys. Please note that there is no way to trap music or sound (other than the bell), thus programs which beep or play music cannot be overridden, and the sound cannot be redirected to the com port. - 2 - CONTENTS 1.

APPENDIX B, LICENSE AND EVALUATION AGREEMENT - 3 - QUICK START A. For a quick start on a DROP to DOS, set up your HOST to call a batch file. The HOST can be almost any communications program set up in HOST mode, or a full blown BBS program set up for remote (see its documentation on how to implement host or remote mode). Use the following line for the batch file it calls: DOORWAY COM1 /S:* /G:ON /V:B^U /M:1000 /B:MSZ /C:DOS This line tells DOORWAY to redirect to COM1, not to look for any user specific file, turn on graphics (and cursor control), use BIOS redirection but allow remote user to switch to DIRECT SCREEN mode with a control "U", allow the user 1000 minutes in DOS, and to load COMMAND.COM and shell to DOS. The /B:MSZ deals with the bottom line, and for best results, one or more of the letters after the colon may be left out. Results will depend on the remote communication package, and whether it is set up for 24 line (with a status line) mode, or 25 line mode. See the section on the /B: switch for more information. B. A quick start on a DOOR for a bulletin board system can be a little more complicated. A good start, however, is one of these: For PCBOARD or a system which generates the PCBOARD.SYS file and does NOT use direct screen writes (writes directly to screen RAM) DOORWAY COM1 /S:C:\PCB /B:MZ /P:PROGRAM.EXT For same as above but uses direct screen writes DOORWAY COM1 /S:C:\PCB /B:MZ /V:D /P:PROGRAM.EXT For a system which generates DOOR.SYS file and does NOT use direct screen writes DOORWAY SYS /B:MZ /P:PROGRAM.EXT For a system which generates a DOOR.SYS file and uses direct screen writes DOORWAY SYS /B:MZ /V:D /P:PROGRAM.EXT The PROGRAM.EXT is the name of the program to put in a "DOOR". The extension MUST be given, and any parameters to be passed to it must follow the filename on the command line. If the program requires cursor positioning, and/or colors for proper operation a "/G:ON" needs to be added in front of the /P: switch to force graphics on. If line feeds are being missed in BIOS mode, then either add a /L:, use ANSI.COM from PC magazine utilities, or use ANSIPAT.EXE on your ANSI.SYS. - 4 - FILES Doorway will look for up to three files. the INITIAL WELCOME, the APPLICATION PROGRAM, and the EXIT MESSAGE. The first and last are simply ASCII (or ANSI) files, and the PROGRAM can be either a .COM or .EXE program. If the INITIAL WELCOME or EXIT message has ANSI codes in it, they will be displayed properly on the HOST and remote ends starting with rev 1.43. A. INITIAL WELCOME FILE This is simply an ASCII or ANSI file which tells the user what he is getting ready to run, and possibly tells him he must set the NUMLOC key and/or have ANSI graphics installed. If any line is started with a $:, then that line will be printed (without the "$:") and a "Y", "N" or [CR] must be entered before the output will continue. This allows you to put pauses into the printing with a: $:ENTER CARRIAGE RETURN TO CONTINUE It also allows you to ask the user if he wants to continue, since if the user enters a [CR] or [Y] to the prompt, DOORWAY will run the application program, but if he enters an [N], DOORWAY will return to the Board or HOST. The last entry in the sequence is the one which determines if the DOOR will continue. The initial welcome can be made into a menu. This is similar to the monitor function seen on RBBS's. When DOORWAY is entered, it can be set up to display a menu of programs to select from. The user enters a number from 0 to 9 or character from A to Z and the program is loaded and run. When aborted, DOORWAY returns to the menu, to let the user select another door if desired. To exit the menu, the user enters either a number or letter which is not defined (such as a "Q"). Example: The batch file: doorway com1 /r:^k /g:on /i:menu The following page shows the actual text of the welcome file with the filename of "MENU". - 5 - The WELCOME FILE (MENU): Welcome to Data World BBS's games doors. Select from one of the following doors. When through, you will return to this menu. To end this doors session, type either 'E', 'Q' or selection 5. 1. Eatumup. A color graphic monster maze game (you need ANSI). 2. 4inarow. Like Orthello. Can you beat the computer (ANSI). 3. Big Rig. Drive a truck across the country (ANSI). 4. Guessit. Let the computer guess something about you. 5. The financial menu 6. Return to board. M:Please enter your selection (1-6): /p:eatumup.exe /t:^C /p:4inarow.exe /t:^C /r:^x /p:bigrig.exe /g:off /p:guessit.exe /i:FMENU Please note that the M:...., and switches must start on the left margin. Note that you can nest menu's now, so that one menu calls another. When the program is exited, it will return to the top level menu. For example, the switch line containing: /I:FMENU will call up another menu which will be presented exactly like this one. See page 26 for an example of FMENU. The M: means that it is to stop and input a selection number. The selection numbers start with 0 and run 0-9, then A-Z. Since a blank line is between the M: line and the first selection, the menu in this case starts with 1. You may need to put a space on the blank line for correct operation. The command line sets the defaults for ALL the programs in the menu. Thus the graphics will be on, and the ^K will cause an external abort in all the programs, unless set differently. 4inarow will also trap for ^C, and Big Rig will also abort with a ^X. Guessit has the main command line ANSI ON directive, overridden with the /g:off. The m:... may also be used. The "M:" and "m:" behave differently on timeouts. The "M:" will return to the menu if there is a keyboard or user timeout, but the "m:" will return to the BOARD. Most likely, if you are reading the PCBOARD.SYS or DOOR.SYS and using the actual user's time, you will want to use the small "m"; however if you are giving, say, only 10 minutes in a door, then the capital "M" would be more logical. You can also password protect any door, or your drop to DOS with DOORWAY. Create a welcome file, and on the last line enter: P:PASSWORD - 6 - For example: Enter the password for exit to dos: P:MONGOOSE Now, if this is in the welcome file for your drop to dos, the user will see the first line, and when he enters the password, dots will echo. If the password is entered correctly, the door, or drop to DOS in this case, will be executed. Otherwise, he will get a message that the password is wrong, and he will be returned to the board. The password may be either small or capital letters, as DOORWAY doesn't differentiate between them. B. APPLICATION PROGRAM The application program can be virtually any .COM or .EXE program. Note that the name of the program to be run, and the path, if not in the same directory as DOORWAY, must be given EXTENSION and ALL. This is because COMMAND.COM is not loaded for safety reasons. Although you could give the program name as "BASIC.EXE APPLICATION", it is not recommended that you do so. If the user was able to break the interpreted basic program, or it were to abort on a critical error, the user would be in the basic interpreter. Then, he could do a shell command which loads COMMAND.COM, and be in DOS. After checking out the BASIC program, then by all means compile it so a break will return to DOORWAY, which will in turn return control to the HOST. C. EXIT MESSAGE This is essentially the same as the INITIAL WELCOME FILE message, but is typed after the application program is run. The "$:" will wait after that line is output, just as in the menu above, but any [Y] or [N] responses will be ignored by DOORWAY. - 7 - INSTALLATION A. BATCH FILE The batch file for DOORWAY should look something like this: DOORWAY COM1 /I:WEL /E:EXM /T:^C /R:^K /G:ON /S:\PCB /P:PROG.EXE The COM (or PORT) selection must be the first command line parameter (unless you are using the DOOR.SYS file), and the program (or /C:DOS if a drop to dos) must be the last, but all the other switches can be in any order. DOORWAY > The DOORWAY program COM1 > The com port number. Can be COM1, COM1:, COM2, COM2:, COM3, COM3:, COM4, COM4:, PORT:AAAA:I, SYS or LOCAL. The COM will be overridden and DOORWAY will run in local mode if the board was signed on locally, and PCBOARD.SYS or DOOR.SYS is found. The SYS tells it to look for DOORWAY's DOOR.SYS instead of PCBOARD.SYS in its current directory. This generic door interface file contains the user's name, port number, time left and so forth. For the actual construction of this SYS file, look at the DOORSYS.DOC file included in this package. Starting with version 2, it will also make use of the "standard" DOOR.SYS file created by GAP and some other board packages. You can use either of these formats, DOORWAY will determine which it is automatically. The additional COM3 and COM4 support allows some COM ports, addressed as COM3 and COM4, to be used with DOORWAY. The address of the UART base address must be found in RAM at 40:4 and 40:6, for DOORWAY to find the ports. COM3 will use interrupt 4 and COM4 will use interrupt 3 (same as COM1 and COM2). If your system doesn't map the addresses of the COM ports into low memory, or the port uses other than these interrupt requests, you will have to give DOORWAY the actual address and IRQ of the COM port. Use the PORT:AAAA:I, where AAAA is 4 hexadecimal digits of the base address of the port, and I is a hexadecimal digit indicating the interrupt number. IE. PORT:03F8:4 is equivalent to COM1. - 8 - B. QUICK SWITCH SUMMARY Switch definition operands /A: ALARM (bell) ON/OFF /B: BOTTOM LINE DIRECTIVES M/S/X/Z Move, Scroll, eXclude, and no linewrap /C: LOAD COMMAND.COM DOS/VIA /D: DISABLE DISK WRITES [NONE] /E: EXIT MESSAGE FILENAME /F: FAST [NONE] /G: GRAPHICS AND ANSI CONTROL ON/OFF /H: HALT SHELLS TO DOS [NONE] /I: INITIAL WELCOME SCREEN (OR MENU) FILENAME /J: DON'T USE VIDEO BIOS; DO IT IN DOORWAY [NONE] /K: KEYBOARD TIMEOUT SECONDS /L: ADD LINE FEED IF ANSI DIDN'T [NONE] /M: MAXIMUM USER TIME MINUTES /N: OPEN FILES WITH NETWORK SHARING [NONE] /O: OPENING SCREEN OVERRIDE (T OVERRIDES DELAYS) T /P: THE APPLICATION PROGRAM WITH EXTENSION PROGRAM.EXT /Q: TELL QUICKBASIC REDIRECTION IS BEING DONE [NONE] /R: CHARACTER TO RETURN TO HOST ON (BREAK PROG.) CHARACTER /S: WHERE PCBOARD.SYS FILE IS LOCATED PATH FOR SYS/* /T: CHARACTER TO TRAP FROM REMOTE CHARACTER /V: VIDEO MODE, AND SWITCH D/B/CHARACTER /W: WAIT AT END OF PROGRAM BEFORE CLEARING SCREEN [NONE] /X: USE THE TRANSLATION TABLE TABLE FILENAME C. DETAILED SWITCH DEFINITIONS /A: Alarm (bell) is enabled on the Board computer if ON, disabled if OFF. If left out, the bell will follow the ALARM setting of the PCBOARD.SYS or DOOR.SYS. Default = OFF. ie. "/A:ON", will override the PCBOARD.SYS or DOOR.SYS setting. /B: /B:X, /B:M, /B:MS, /B:Z. These codes deal with line 25 of the display in ANSI mode only. If the application program tries to position the cursor to line 25, some modem programs, such as QMODEM, ignore the request, since line 25 contains the MODEM's status information. This can be disastrous for some games which write a status also on this line, since it will appear randomly on the user's screen. The /B:X will simply not send any characters which are on line 25, and the /B:M will move the characters to the line above (line 24). If things go badly when the cursor gets to the bottom of the screen, try adding /B:M to the command line. Generally, you will want this switch for a drop to dos function, if you are using a com program which will not allow you to eliminate the status line. However, if your com program (Such as QMODEM 4.0) does allow you to eliminate the status line, it is highly recommended to do so, and not use a /B:M. - 9 - Versions after 1.2 now send a sequence which will position the cursor at the bottom of the screen for both 24 and 25 line modem programs. For maximum compatibility, it is highly recommended to put this switch in for ALL door programs, unless it specifically causes a problem. Also, since line 24 and 25 will be going to line 24 if you do a /B:M, you will want to put a /B:MS on a drop to dos and some text programs. This tells DOORWAY to scroll the screen when it moves the line from 25 to 24 (BIOS mode only), if the last line written was line 24. Otherwise, you may find that line 24 gets overwritten once, when text is being printed. If you are using the /L: and /B:M, this will already be taken care of by the /L: switch. A "Z" can also be placed in this sequence. It tells DOORWAY to NOT write the very last character of the bottom line. Some programs will write a character there, quite often a space, making the remote's screen scroll, when it shouldn't. Obviously, you will be missing a character on the right of the screen if you do this, and a character is supposed to go there. If the comm program on the remote end scrolls when the bottom right character is written, then it will be absolutely necessary to use the "Z". /C: /C:DOS or /C:VIA. The /C: will cause COMMAND.COM to be loaded. The /C:DOS will then exit to DOS and allow you to perform DOS functions over the modem. Enter "EXIT" to return to the board. You should make sure you are back in the same directory you dropped to dos in before exiting. The VIA function will load the program (or batch file) via COMMAND.COM. I see no need to do the latter function, but it is available, if absolutely necessary. If you load a batch file and it gets broken, a user could get to your dos. This is recommended for sysop functions ONLY! If you load via command.com, then path searching will be supported and the path and extension of program name need not be given. Obviously, the DOS function is not for a door at all, but for a REMOTE drop to DOS function. You can do a DOORWAY /G:ON /C:DOS, either in a high security door, or in the REMOTE batch file for remote drops to dos. /D: Disable Disk writes. This switch will intercept all DOS calls and not allow disk writes to take place. This can be handy for a program like a game which insists on writing a score file. It may cause problems for programs which require writing to disk to run. /E: Name of the EXIT MESSAGE file. No message if left out. - 10 - /F: Fast. Functional only if Graphics is 'ON' and in non-direct screen mode. Some programs move the cursor all over the place between characters written, (Quick Basic compiler tends to do this). Each new locate of the cursor normally generates an 8 character ANSI sequence to send out the modem. For some games, this unnecessarily slows down the action. The /F: will not send ANY ANSI sequences on a cursor locate until a character is ready to be written. However, since cursor relocates are not done until a character is to be written, this gives the strange effect of not seeing a Carriage Return have any effect until a printable character is sent to the modem. It also has the strange effect of having the cursor one right of where you would expect, if you enter backspaces over something. /G: ANSI GRAPHICs enabled if ON, disabled if OFF. If left out, it will be as defined in the PCBOARD.SYS file. Default is ON. /H: Halt shells to DOS. You may want to put a program into a door which allows the user to shell to dos (such as LIST). This switch will prevent the program from doing a shell to DOS. Since a program may do a shell in a non-standard way, be sure to verify this is operational with any program before making it available to general users. If the alarm is "on" DOORWAY will beep the HOST if anyone tries to shell DOS. /I: Name of the WELCOME MESSAGE file. No message if left out. /J: NON-IBM compatible BIOS. This may have to be used if a CLONE BIOS which is not really IBM compatible is in the host, or an EGA/VGA BOARD installs a NON-COMPATIBLE BIOS. If you are missing CRLF's in NON-DIRECT mode, try this switch. Not active in DIRECT WRITE MODE. /K: KEYBOARD TIMEOUT TIMER. The /K: will accept a number between 0 and 255 to define how long, after the last character was received from the remote or local keyboard, to wait before terminating the door and returning to the board. The /K:0 is a special case which will override keyboard timeouts totally, (recommended for drop to dos). Also, an operand of "V" will reset the keyboard timer on each character which is sent out the port. This is useful if you have a door which sends out 10 minutes of text with no keyboard input required. The user would otherwise be kicked out of the door after about 4 minutes, since he hadn't entered anything. Do not use a /K:V on something like eatumup though, since the continuous movement of the monsters will keep the keyboard from timing out. A /K:100V will give a 100 second timeout, and reset the timer on video. - 11 - /L: Add line feeds when cursor is positioned at the bottom of the screen. Various ANSI.SYS's handle the scroll differently when they get to the bottom of the screen. Some do not do a BIOS scroll, but do the scroll directly without doing a BIOS interrupt. Thus, if you do a DIR in DOS, it will work until you get to the bottom of the screen; then, all further lines will overwrite the bottom line. The /L: will check for the cursor being addressed at the start of the bottom line and add a Carriage Return, if it is there. If you have an ANSI.SYS which does the BIOS call, you will get double line feeds if you add this switch. Another way of fixing this is to use a different ANSI.SYS, or try the ANSIPAT patch on your ANSI.SYS. It should work on most MSDOS's. It is recommended to use the ANSIPAT, if it will work, and leave this switch out. ANSI.COM from PC Magazine is a very good alternative. It is not necessary to use this switch in direct screen mode. /M: Maximum door time allowed. This will override the time computed from the PCBOARD.SYS or DOOR.SYS file. It is in minutes and has a maximum value of 32767 minutes. Default is 10 minutes. Negative values will cause an immediate abort. NOTE - This is functional on registered versions ONLY! The demo version will always default to 10 minutes. /N: NETWORK. If the /N: switch is set, all files will be opened network compatible. Both the initial welcome, and exit messages will be opened share compatible, and if the program being shelled opens a file, DOORWAY will change its open command to a share compatible "Allow read - deny write" open command. Note that the PCBOARD.SYS/DOOR.SYS file is closed immediately after reading it, so there is no longer a problem accessing these from the program being shelled. Some COMMAND.COM's have a problem with this, so if you experience lock-up's on drop to DOS, try eliminating this switch. /O: Override the DOORWAY title screen. This can ONLY be done after registering your copy of DOORWAY. A /O:T will also eliminate the delays associated with the opening screen (recommended for drop to dos). See REGISTRATION below. /P: The program name with the extension and path if not in the default directory. This MUST be the last switch on the command line. Anything following the program name will be passed to the program as a command line parameter for that program. This is not used for a /C:DOS switch. - 12 - /Q: This switch tells DOORWAY that the program being shelled is a Quick Basic v. 4 or later program. Doorway will intercept the DOS calls and tell the program that its output is to be redirected. Without this switch, these programs will not send characters out the com port, since they will do direct screen writes. If a program will not send characters out the com port under DOORWAY, but can be redirected by CTTY, Gateway or the ">" symbol, then this switch should make DOORWAY redirect it as well. Note that a program expecting redirected output may not send things like colors, and cursor relocations. Do not use this switch with a drop to dos, as COMMAND.COM seems to have real problems with it. Starting with DOORWAY version 2.0, we support direct screen writes. You may want to experiment with each program and determine if performance is better in direct screen write mode, or with this switch. /R: RETURN. Each of these defines one character with which to abort the program. The character, with which to abort, will be the control equivalent if preceded by a ^, such as a ^C, for an ASCII 3. If the user enters the control character, the sysop will see "EXTERNAL USER ABORT" displayed. If the Sysop enters the return character, then the user and Sysop will receive a message which says, "THE SYSOP HAS REQUESTED YOU TO RETURN TO THE BOARD", and the program will be aborted. /S: Where to look for PCBOARD.SYS. ie. \PCB\. Doorway can tell if the PCBOARD.SYS is version 11-12 or version 14, and will read and interpret each properly without being told. If left out, then it will look in the same directory that DOORWAY is in. If not found, then the Graphics, Alarm, User time and User name settings will default to their "DEFAULT" settings. Thus, this program is compatible with RBBS, WILDCAT, GT, OPUS, RYBBS, QBBS, FORUM and GENESIS as well. For those of you who are running other than PCBoard, I have made it so that the search for PCBOARD.SYS can be totally over-ridden. Simply enter an /s:* on the command line and the delays associated with looking for PCBOARD.SYS and displaying the "not found" message will no longer occur. Note that to reliably run on RBBS, you must set RBBS up to drop to dos and not shell for doors. You can also look for a generic door file instead of pcboard.sys, by placing a "SYS" where the com port normally goes in the command line. Do not use the /S: parameter with SYS. /T: Each of these defines a character to trap out of the input. If there is a ^ in front of the character, it will look for that control character. A ^@ will trap all extended codes (See below). - 13 - /V: This is the one you have all been waiting for! Go into direct screen write mode. Instead of redirecting the BIOS calls for VIDEO, this will tell DOORWAY to check the Host's screen against an image DOORWAY maintains. When it sees a difference, it will send it out the modem. A /V:D will put it in direct screen mode, a /V:B (the default) in BIOS call mode. You can add an additional character to allow switching between modes, such as: /V:D^U will start out in direct screen mode, but allow you to toggle between modes with a control U (on remote end only). A screen redraw can be accomplished by switching to BIOS and back to DIRECT. It is highly recommended NOT to use anything other than a 25 line mode on the com end for this, on a drop to dos. A /B:Z will be necessary, if your com program doesn't support mode setting via ANSI. Otherwise, the remote screen will scroll when the cursor reaches the bottom right of the screen, and the remote end will get very messed up. When a large portion of the screen has changed, DOORWAY checks to see if the screen scrolled, and if it did, sends a scroll to the remote. DOORWAY will check for up to 5 scrolls. If the HOST gets more than 5 scrolls ahead of the remote, then DOORWAY will start rewriting the screen. If this happens, you may want to enter a ^S, and let the remote catch up with the HOST, so they can get resynced. It is highly unlikely this will be necessary with the changes made in version 2.03 (Enter a ^Q to restart). Redirection of the Host's screen occurs when there are keyboard or timer interrupts. Thus the remote will be updated as quickly as possible when the program is waiting for a keyboard interrupt, and will still redirect, although more slowly, when not checking keyboard interrupts. /W: If you put in the /W: switch, it will pause at the completion of a program. It will not pause if there is a carrier loss, or if the program was terminated by the Sysop (Sysop has requested that you return to board). /X: This will load and use a translation table. The translation table can be generated and modified by using the included XTABLE.EXE program. Additional information can be found in the translation table documentation included in this ZIP. The translation table allows redefining any and all keys from the remote to the host. Thus, if a program requires entering an [F10] to exit, you can remap it to say a ^Q (control Q). Some programs such as QEDIT use both the character and the scan code for proper operation. Starting with version 2.00, DOORWAY now supplies scan codes to the HOST's program. For instance, entering the ESC key will put QEDIT into command mode, but entering a ^[ or ALT 27 will instead cause an escape character (back arrow) to be sent to the text file. - 14 - Of course, if an ESC character is received over the modem, there is no way to tell which of these 3 methods were used to generate the ESCAPE. DOORWAY has a default set of scan codes, so when it sees an ESC, it tells QEDIT the ESC key was pressed. If you want it to tell QEDIT that a ^[ was pushed, then remap the ESC or some other key to a ^[ ESCAPE with XTABLE.EXE. Several other keys are handled differently, most notably, the two sets of numbers (DOORWAY defaults to the ones at the top of the keyboard), and the two "-" and "+" signs (DOORWAY defaults to the white ones). For information on XTABLE, see the XTABLE.DOC file. If you are running out of room on the command line (DOS only lets you put 127 characters on a line), you can eliminate the colons after the switches. It makes reading the line more difficult, so it is not recommended to leave them out unless you really need the space. RECOMMENDED STARTING SETTINGS GENERAL PURPOSE DOORS BIOS calls /B:MSZ for text oriented (screen scrolls) like adventure games /B:MZ for screen oriented (no scrolls) like EATUMUP DIRECT SCREEN WRITES /Q: /B:MSZ or /Q /B:MZ as above /V:D /B:Z DROP TO DOS BIOS CALLS /B:MSZ (IF USING 24 LINE COM PROGRAM) /B:Z (IF USING 25 LINE COM PROGRAM) [NONE] (25 LINE, AND COM PROGRAM WORKS) DIRECT SCREEN WRITES /V:D /B:Z or /V:D (DEPENDING ON COM PROG) - 15 - MULTITASKING DOORWAY now supports TaskView and other multi-Tasking environments. You need not even inform DOORWAY about the Multi- tasker. In some cases, you may be unable to use direct screen mode with multi-taskers. EXTENDED KEYBOARD CODE SUPPORT DOORWAY supports all extended character codes! This allows you to send it the Function keys, Cursor keys, and ALT functions. Undefined codes and the Ctrl PrtSc code are trapped from going to the program, since some undefined codes can crash the system. If you want to override all extended codes, then enter a /T:^@ on the command line, as this will then trap the NULL character. At this time, there are several modem packages which support extended keyboard codes. The following table lists those which claim to have DOORWAY capability. The comm programs either go into DOORWAY mode by entering an ALT character, such as ALT "=" (internal), or by loading a DOORWAY keyboard definition file. Keyboard definition files are sometimes included with the comm program, or can be downloaded from most BBS's. If your favorite modem program doesn't support extended key codes, you might mention this much needed function to your favorite modem software vendor! Starting with version 2.05, DOORWAY also supports the enhanced keyboard. If the com package is capable of sending the enhanced keys from remote, then doorway will return them to the program on the HOST if an enhanced keyboard call is performed. Note that if the HOST does not have an enhanced keyboard, any program on the HOST is highly unlikely to ask for enhanced codes, and will therefore not get them. Standard extended codes are encoded as a NULL followed by the SCAN CODE. E0 enhanced extended codes are encoded as "NULL EOH SCANCODE". DROP TO DOS OR REMOTE CAPABILITY Many people are now using DOORWAY for a remote drop to DOS or remote redirection program. This can be done with the following command line for either your drop to dos door or remote batch file: DOORWAY COM1 /i:pword /g:on /a:on /m:100 /v:d^U /s:* /c:dos I like to turn the alarm on, so if anyone gets into my dos I will hear any beeps. You will need to use a com program which supports 25 line mode. The above also sets ANSI graphics on. The /m:100 gives me 100 minutes in dos, and the /c:dos tells it to drop to dos. The /i:pword allows me to check a password before an exit to dos is allowed, and may be left out if desired. See the discussion on the password in the initial welcome discussion above. The /V:D^U puts it in direct screen write mode, for compatibility with virtually all programs I may want to run, and the ^U lets me toggle between the modes, for a screen redraw if - 16 - nothing else. You may need a /B:Z, depending on whether your com program handles the "^[[7l" ansi sequence or not. (If you see a "^[[?7l" or "^[[?7h" tell the author of your com package.) A /B:M will be needed, if you are unable to eliminate the status line on the remote end. The reasons for using DOORWAY for your drop to dos are many. Here are a few of the more obvious ones: CTTY GATEWAY DOORWAY Redirects BIOS writes no no yes Redirects direct screen writes no no yes Generates ANSI codes no yes yes Smart ANSI generation (clear EOL's) no no yes Allows external aborts no no yes Works with multi-taskers no yes yes Allows function keys to be sent no no yes Allows cursor keys to be sent no no yes Allows keyboard redefinition no no yes Allows password protecti on no no yes Allows trapping of characters no no yes Monitors carrier no no yes Monitors user time no no yes Abort on keyboard timeouts no no yes Handles 24 line com programs no no yes Reads and uses pcboard.sys or DOOR.SYS no no yes Allows you to externally abort pgms. no no yes Gives 24 hours support via BBS no no yes Allows you to inhibit disk writes no no yes Some of the PCBOARD 12.1 utilities require you to do a SET PCB=/BIO to make them do BIOS writes. I would put this line in the batch file for your drop to dos, just before the DOORWAY line, if you are using a BIOS drop to dos and PCB 12.1. PCBOARD will remove this from the environment when it is run; therefore, it needs to be set each time you do a drop to dos. With this set, the PCBSETUP can be run from remote if you are using a modem package which supports the extended key codes. The cursor, page up and page down, and function keys will all be handled as if entered on the board keyboard. You can move around the pages, and also enter the ALT F to find a string. In dos, the F3 will repeat the last command and in EDLIN, you can use the F3, cursor, ins, and delete keys, just as you would at the main keyboard. The PCB=/BIO is not required for PCBOARD 14. You will find you can do lots of things which CTTY disallows. Try a "COPY CON: FILENAME" with CTTY and it will lock up, but works fine with DOORWAY. To exit the COPY CON: enter a ^Z. Once you get used to a DOORWAY remote drop to dos, you will wonder how you got along without it. - 17 - USER ABORTS AND LOST CARRIERS If a user enters one of the characters following the /R: in the DOORWAY command line, then the program will abort. "EXTERNAL USER ABORT" will be displayed on the Sysop's screen for a couple of seconds. Note that if the user does an EXTERNAL ABORT when the program is in a CRITICAL DOS function, the abort could crash the system. Therefore, if a critical DOS function is being performed, the abort will be put off (but remembered) until it is safe to abort. If the user does an external abort during a drop to DOS (REMOTE session), the function or program in process will be aborted, and the user will be dropped back to DOS, and the message "EXTERNAL ABORT IN DOS" will appear on both ends. If a carrier is lost, the program will abort and return to the HOST program automatically. The message "CARRIER LOST >>>>> RETURNING TO BOARD" will flash up on the HOST's screen. If carrier is lost during a critical DOS function, DOORWAY will attempt to abort the program for 255 seconds. DOORWAY goes to great lengths to abort a program which was previously unbreakable. It will resort to hooking the dos interrupts to gain control, and sending the program carriage returns, ESC characters, and ^C's. If unable to break the program for 255 seconds, then the system will reboot. The only way I know for this to happen, is if there is a critical DOS error and the system is waiting for an input with "RETRY, ABORT,or IGNORE". If this happened, and the user hung up, then the system would be hung until the Sysop noticed it and entered an "A". Therefore, Doorway will reboot the system, as there is really no other solution. Likewise, if a carrier is lost while in DOS, the system will abort and the message, "CARRIER LOST --> REBOOTING" will flash up to the screen. The reason for this may not be so obvious. First, you don't abort from DOS the same way as from a program, DOORWAY would have to fake an "EXIT" being entered at the keyboard. Second, Doorway has no way of knowing if you are in DOS or running a program from DOS, which would have to be aborted first. If a User or keyboard timeout occurs, then DOORWAY will send the appropriate message and return to PCBoard. If a keyboard timeout occurs in DOS (/C:DOS), then the bell will be rung, but it will not reboot. - 18 - REGISTRATION This DOORWAY program is strictly a non-registered demo-version. The exact terms of this agreement are given fully in APPENDIX 2, but the following is a "plain english" condensation. This non- registered version may be freely distributed and uploaded to BBS's. It can be tested and used for one month. After that date, the program may not be used, unless it is registered. You may register it several ways. First, you may fill out the order blank at the end of this book and send with $30 to: Marshall Dudley 406 Monitor Lane Knoxville, Tn. 37922 Second, you may call Data World BBS, and go into the DOORWAY registration door (DOOR 18), which will allow you to register your software on-line in only a couple of minutes. You will receive your registration number while you wait. Be sure and have either your VISA, MASTERCARD, DISCOVER, or AMEX card handy before entering the door. Please note that using a false or stolen credit card number is a crime. When you register, you will receive a Registration number for your copy of DOORWAY. This number will be valid for your board for all future versions of DOORWAY, no matter when or where you get them. You will be registered in the DOORS conference on Data World BBS, and given complete support (If you don't get registered, leave a message to the sysop or page him). Defeating the registration, or distributing a registered version of DOORWAY is illegal. Make sure that any copies of DOORWAY you make available for others are NON-REGISTERED! Violators will be prosecuted. If you have any questions or comments, feel free to contact the home board: Data World BBS 615)966-3574 (Private Node 2 and node 3 for registered users 615)675-3282, and 615)675-4577) Nodes 1 and 2 use Hayes 9600 V modems. Node 3 is 2400/1200 baud. Once you have your registration number, go into the subdirectory that DOORWAY is in and type "DOORWAY REGISTER". DOORWAY will ask for your board name. It must be entered EXACTLY as registered, including spaces and any punctuation (although capital and small letters can be interchanged) . Then, enter the registration number you have gotten, and it will automatically register the software to your board. The operation of DOORWAY will change as follows when registered: UNREGISTERED REGISTERED REGISTERED TO: [UNREGISTERED COPY!] YOUR BOARD NAME Time in DOOR: 10 Minutes PER SYS file or /M:TIME Registration screen Displayed to the Sysop Omitted /O: option Not available Operational - 19 - DOORWAY REGISTRATION ORDER BLANK Please fill out the following if you are ordering DOORWAY registration by mail Name___________________________________ Board's Phone # _____)____-_________ Address _______________________________ City, State Zip _____________________________________ Board Name (Must be EXACTLY as you want it to appear to your users-60 chr. Max) _______________________________________________________________________________ Revision of DOORWAY you presently have __2.05___. Mail orders will receive a disk with the latest released version of DOORWAY and your Registration number by return mail. Note: Personal checks drawn on Canadian banks should be made out in US $, and an additional $2.00 should be included to cover the additional collection fees (no additional charge for Cashier Checks or Money Orders from Canada made out in US $). Send to: Marshall Dudley 406 Monitor Lane Knoxville, Tn. 37922 - 20 - QUESTIONS AND ANSWERS Q. I have typed DOORWAY LOCAL, but all it does is print a screen of information and return to DOS. A. DOORWAY is not a door itself. It turns other programs into a door. Thus, unless you are using it for a drop to dos, you will need a /P:FILENAME.EXT as the last switch on the command line. Q. I am using DOORWAY for my remote drop to dos. It seems to work fine, except when a directory gets to the bottom line of the screen, one of the lines gets overwritten. Also, back spaces do not work on the bottom line, but become spaces instead. A. You are using a communication program which places a status line on the bottom line of the screen. Therefore, attempts to address the cursor on the bottom line are being ignored by your modem software. This is not a DOORWAY problem, but DOORWAY will solve it if you put a /B:MS switch in the command line. Q. DOORWAY used to work great for my compiled BASIC programs. Now it won't send the characters any more. A. You have moved from QUICK BASIC 1, 2 or 3 to QUICK BASIC 4, or Turbo Basic. The compilers have quit using the MSDOS/IBM specifications for sending characters to the screen. Instead of using DOS or BIOS interrupts, they are writing to the screen memory directly. Thus, it is impossible to redirect by normal means. Either include the (Q)uick Basic switch "/Q:" in the command line, compile with a pre-4 version of QUICK BASIC, or set up DOORWAY to use the direct screen mode (/V:D). Q. I am using DOORWAY for my remote drop to dos also, but when it gets to the bottom of the screen on a DIR listing, I don't get ANY more line feeds, and all lines overwrite the previous lines on the bottom. A. There are several versions of ANSI.SYS. Some are better behaved than others. Some of them do NOT do a BIOS scroll when they get to the bottom, but instead do a block move in video memory. DOORWAY has no way of trapping this "blind scroll". Therefore, DOORWAY can be made to send a line feed when it appears that a scroll was done. Just insert a /L: in the command line to get it to insert extra line feeds. If you put this switch in and don't need it, you will get double line feeds at the bottom. A better solution is to try the ANSIPAT in this ZIP. It should work on most MSDOS's which exhibit this problem. DOORWAY 1.45 has been made compatible with ANSI.COM, the PC magazine ANSI driver, and is a very good substitution. Q. I can't seem to get DOORWAY to give me more than 10 minutes before it aborts. It even reboots if I am in DOS. - 21 - A. Either you don't have a registered version or else DOORWAY cannot find PCBOARD.SYS, and you have not defined a maximum time on the command line with a /M:XXX (where XXX is the time in minutes). It is assumed that, if time expired on a user in DOS, something is VERY wrong, and that he/she probably shouldn't be there. Therefore, the system will reboot, hopefully before any harm has been done. Q. DOORWAY seems to work fine, but when it is through, the board doesn't come back up. A. Check your Board documentation for how to implement doors. For PCBOARD, you need to place the line "BOARD" (or whatever you named the board's batch file) after the "DOORWAY XXXXXX" line. This will be different for different board softwares. See the example .BAT files for guidance. For RBBS, it is not recommended to shell to DOORWAY. Q. DOORWAY seems to work from the board end, but gives and receives no response from the modem. A. Check that you have defined the correct COM: port in the command line. Q. When I run a particular program during my remote drop to dos, it seems to hang up when I exit. If I enter a character, I get a beep, and everything starts working again. What is happening? A. Your program is turning off the com port when it exits. Doorway now monitors the com lines during timer ticks. When a character is entered by the user and not fetched for over .5 second, DOORWAY will reopen the com port and send a beep. Q. When I run DOORWAY, many programs will not send anything out the com port, but user entered characters are received ok. What's the problem? A. You are using an "ENHANCED" ANSI driver, such as FANSI, NANSI, or ZANSI. These do direct screen writes instead of BIOS calls, so DOORWAY never sees the characters go to the screen. Replace the driver with the ANSI driver which comes with DOS or ANSI.COM from PC magazine. Also, the programs you are running may be doing direct screen writes. These can not be redirected normally. You may try putting a "/Q:" in the command line to see if it will support redirection of output, or set up DOORWAY for direct screen write mode (/V:D). Q. Why do you read everything from the command line instead of from a config file like everyone else does? A. I have never liked to add a bunch of files for any application. The config file would be different for each door, and if you are using DOORWAY for 10 different doors, that would add 10 more files. Also, when modifying a door, it - 22 - is more confusing to trace the names though different files to determine which config. file should be modified. Lastly, it takes time to load the config. file, and as we all know, doors are slow enough as it is. Q. I am very confused on the order of the switches in the DOORWAY command line. A. There are only two things which have to be in any particular place. The COM1, COM2, SYS PORT or LOCAL must be the first item after DOORWAY, and either /C:DOS or /P:FILENAME.EXT must be the last switch on the command line. Q. I am using DOORWAY in direct screen mode. when the cursor gets to the bottom of the screen, the screen gets really messed up. What can I do? A. You either have a 24 line com program running, or your com program isn't translating the "don't wrap line" ansi sequence. Use a 25 line com program and use a /B:Z or a version of the com program which supports the ansi. Q. I have registered DOORWAY, and now I find a later version on a local board. Do I have to register it also to use it? A. Your registration number is good for all future versions of DOORWAY. Simply register it just like you did your earlier version. If you have lost your number, then type DOORWAY REGISTER on your earlier version and it will give your board name and registration number back to you. Be sure you have your registration number before copying the new version over the old! Q. I registered DOORWAY some time ago. Now I notice the price is higher for the new version with direct screen write capability. I think it is well worth it, but do I need to send the full $30 or just the difference? A. We have always said that if you register DOORWAY all future versions are free. We stand behind our word. You supported us when we had less to offer and it is only fair for us to support you. There is no additional charge. Q. I have had to change my board name. I have already paid for DOORWAY but now it says "REGISTERED TO:" my old board's name. What can I do? A. Once we verify that you have really changed the board name, you can get a new registration number for the new name. Note that the old name and registration number will no longer be valid and it will be illegal to use them. Q. I am running multi-nodes. Do I have to register more than one copy? - 23 - A. If all nodes have the same board name, and are at the same location, then one registration is all you need. (who else does that????). If you are using the program privately for a remote utility, it can be placed on multiple machines AS LONG AS NO MORE THAN ONE COPY HAS A POSSIBILILITY OF BEING RUN AT ONCE. For instance, you could put it on both your computer at work and at home, so you can log in either way. This does not mean that a company can have a copy on a BBS and all the employees can take it home. Q. When NOT in direct screen write mode, all the Carriage/Return Line Feeds are missing, when doing a drop to DOS, and with some programs. A. Your Video BIOS does not follow the IBM standard. It can be either the BIOS which came with your computer, or if you are using a EGA or VGA, it may be the BIOS which this board loads (Paradise VGA PLUS, for example). Try putting in the /J: switch to tell DOORWAY to not expect compatibility. Q. Why should I register DOORWAY? A. It allows you to do some other things not available if you do not register it. Also, I have spent hundreds of hours creating a good package which is needed by the BOARD community. Future changes to PCBOARD and compilers can make door programs not work anymore. The only way I can continue supporting this product is if those who are using it support my efforts through registration. Let's be honest. The closest thing to this program will cost you over $300, so $30 is a very good deal. If you put 10 programs into DOORWAY, that is only $3.00 each, and for a remote drop to DOS, it is unmatched. User support is directly responsible for the latest version with direct screen write mode. I would like to give many thanks to those who have supported us. Q. When in DIRECT SCREEN WRITE MODE, the screen is 1 line higher than when not in DIRECT SCREEN MODE. Why is that? A. You are using the /B:M or /B:MZ. The host has 25 lines which have to be mapped into 24 lines on the remote end. When using BIOS mode the bottom line is "moved" to line 24, overwriting it. If you put in a /B:MS or /B:MSZ, the screen gets scrolled first so it won't overwrite. In direct screen mode, the writing of the screen and the redirecting of the characters are totally asyncronous with each other. Moving the output up 1 line, and eliminating the top line, is the only way to avoid creating a real mess. If this creates problems, try eliminating the bottom line with a /B:X. - 24 - Q. I can't seem to get DOORWAY to work with 4DOS. What am I doing wrong? A. Doorway will work with 4DOS, except 4DOS will use the ^ as an end of line. Therefore, you cannot use a ^ in the DOORWAY command line, or you will need to set up 4DOS to use something other than a ^ of this function. Q. How do I get DSZ to work under DOORWAY? A. The problem with using DSZ under DOORWAY is that the block transfer information, which DSZ writes to the local screen on the HOST, is being sent out the modem with the data, thus causing CRC errors. The simple solution is to redirect the screen output to NUL like: DSZ port 1 speed 1200 pB4096 rz > NUL DSZ port 1 speed 2400 pB4096 sz > NUL Q. When I type DOORWAY REGISTER the computer locks up. What am I doing wrong? A. You probably have a memory resident program which is not handling the keyboard interrupt properly. I have been informed that QUICKEY will cause this problem. - 25 - APPENDIX A It has been reported that some systems (on the remote end) will not work properly if they have been switched to 30 line mode and back to 25. I don't have any more information on this. You will have to reboot and reload your com package if you have this problem. Many of the communications programs have recently added a DOORWAY mode. The following lists the programs which have the capability to send the extended key codes, such as the Function Keys, Alt keys, and cursor keys. Internal means that a simple key entry will put the program into "DOORWAY" mode. Key file means that there must be a key definition file which must be loaded to implement this capability. The key file may be distributed with the communications program, or may have to be downloaded from a bulletin board. Generally, using a key file is more complicated than if it is implemented internally. Comm.
