DarkTerm V4.0 - By Alan Peters ------------------------------ (C) 1986 DarkStar Systems Software NOTE: This program is in the public domain, and may be given away, but may NOT be sold, nor may the main code be altered in any way. DarkTerm 4.0 is yet another enhancement of the previous version, 3.0. This new version is more compact, and offers some new features: - Xmodem Sum and Xmodem CRC protocols, with automatic padding removal, and CIS .IMG removal. - Multi-Page phone directory with multi-number sequence dialing. - New editor link file, for sequential text editing. - Modem Modules, files that contain all the basic modem communications routines, so that compatibility may be offered to the benefit of the user. - Accurate 1200/2400 baud rates, with a 200-600 baud range as well. - Increased buffer capacity (32k). This version was designed to go along with the DarkStar System 3 BBS programs, 2 very powerful, all ml BBS's that run in FULL color, or ASCII. If you want more info on these great programs, see the end of the docs. Loading The Program ------------------- V4.0 will load off any type of drive and off any device number, as long as the drive number is "0", not "1". Type LOAD"DARKTERM 4.0",device #,1 to load this program. After loading, the program will be set up according to DT4.SETUP file. If that file does not exist, or it does exist in it's original format, then the term will operate on the default settings that these docs are based on. The program has 2 modes of operation. The first status indicator at the bottom right will be either inversed, or normal. If it is inversed, you will be in command mode, where all commands that use the Commodore (C=) key will be functional, as will be the function keys. Otherwise, all commands and function keys are inoperative. Use SHIFT/RETURN to toggle between command mode, and normal mode. To do anything on the terminal, you will usually have to be in command mode. That same indicator will be either an A or a C indicating ASCII or COLOR terminal modes. SHIFT RUN/STOP will toggle between color and ASCII. Color mode is the same as it always was with previous DarkTerms, but it never hurts to refresh memories, so: C= 1-8 and CTRL 1-8 will change the cursor color. F1 and a color key (ie., F1, then CTRL-1) will set the border color. F3 and a color key will set the background color. F5 and a color key will set the foreground color. CTRL-I enables the UPPER-CASE/GRAPHICS character set at $E000 (57344). CTRL-H enables the UPPER & LOWER CASE character set at $E800 (59392). CTRL-G is the bell tone. Cursor Up, Down, Left, Right, Clear, Home, RVS On/Off all operate like the normal 64 screen editor. RETURN will remove all characters on that line after the point of return. INSERT will insert only on the current line; the same goes for delete. The ASCII mode may not appear to be ASCII when you are in half duplex, and you try typing. But it is, despite the fact that you can cursor around. NOTE: You can NOT send screen colors with F1/F3/F5 when you are in command mode, or you will send a function key string. Status Indicators ----------------- 00:00a 00:00:00 32768 01-01 A:B:H:I:U:W 1 2 3 4 5 6 7 8 9 0 1: Clock. Standard Am/Pm clock. 2: General purpose timer. This timer will be cleared whenever a carrier is detected from auto dial or auto answer. 3: Buffer Bytes Free. This is 32768 bytes when there is no phone directory in memory. This will count down to zero, and stop if it gets there. 4: Cursor row/column position. This is for the benefit of color mode, when one wishes to screen map when writing messages on the CBBS, or use hidden cursor movement. 5: ASCII/Color and Command Mode status. As explained above. 6: Buffer open/close. Use C= O to open and close the buffer. The buffer is open when the status flag is inversed. 7: Hide Screen Output. Use C= H to toggle. When inversed, all output to the screen is suppressed. However, if the buffer is open, data will still be sent to the buffer. This is useful for buffering data that you don't want visible on the screen. 8: Modem Input/Output Inhibit. Use C= I to toggle. When inversed, all input and output with the modem will be put on hold, while the carrier will remain in it's current state. 9: Upper Case Lock. Use C= U to toggle. All letters from A-Z will be in CAPS when this flag is inversed. 0: Word Wrap. If you are logged onto a system that runs at 80, 132, 160, or some other screen column format more than 40, then use C= W to enable wordwrap, and no words will be broken up on the right side of the screen. There are several other commands available, and each will be described in detail. When in a sub-menu of any command, use the RETURN key to get back to terminal mode, and if that doesn't work, use the STOP key to return. Auto Dial / Auto Answer (C= A) ------------------------------ Both auto dial and answer work according to the routines in the modem module file. See the notes at the end for how to create a modem module. Auto dialing here will only dial one number at a time, and will redial that number until a carrier is detected, or the STOP key is hit to abort dialing. A . string of 18 digits is acceptable for input. In the 1650 version, only numbers are dialed, and all other characters are skipped. Auto answer will answer at the current baud rate until a carrier is detected, or the STOP key is used abort. If you want multiple autodialing, use C= P and the phone directory. Buffer Options (C= B) --------------------- <A> Append Buffer To File. <C> Clear Buffer. <E> Edit Buffer (See Below). <L> Load File Into Buffer. <M> Merge (Add) File To Current Buffer Contents. <P> Print Buffer. (ASCII Or Normal). <R> Review Buffer (See Below). <S> Save Buffer. <T> Transmit Buffer. B:00000 - Buffer Byte Count. Transmitting buffer contents will operate according to the transmit delay factor set in modem options (see C= M). When you turn on transmit buffer, you will be returned to color/ascii terminal mode, and the buffer will begin to send. You will most likely need a delay factor when sending, or the data may be garbled when sending pre-written messages to a BBS. The CBBS-3 can usually accept text with an xmit delay of 50 or less. Once the buffer xmits, you can use any command mode keys, since the buffer transmit is running in the background. Use SPACE to pause buffer send, and STOP to abort. You may not send a buffer IF: you are sending a function key, or, you have the buffer already open to accept data. Editing a buffer operates in the same manner as writing a message with CBBS-3. You will be placed in the editor, and anything you type will be buffered. You may write color messages, using screen colors, etc., as described above, or anything else. When you are writing text, the message "Buffer Edit On..." will be displayed. To exit buffer edit, use the STOP key. If you want to delete the current character from the buffer, then use CTRL-D, NOT delete, as delete will be buffered. When you are in the editor, you may not be at the end of the text data that it contains. Ie., if you write some text, exit, then select edit again, you will be at position 0, where the text may be at position 1234, the end of the data. Thus, entering any data now will in effect overwrite anything currently at that position. Using CTRL-D Now will erase the byte at position 0, and shift the entire buffer after that, from 1-1234, one position down, until the entire buffer has been justified. I will not explain what happens; you will have to try it yourself. Also, CTRL-X may also exit like STOP, BUT this has the effect of TRUNCATING the remainder of the buffer data, from the current position onwards. When you are in review mode <R>, you will be able to read the buffer, but you may STOP at any point using the SPACE bar, or abort using STOP. CTRL-X will allow you to re-enter the buffer at the position you stop at when you hit CTRL-X. Note that the character position stopped at is actually one past the point of re-entry. Ie., you hit CTRL-X in the middle of the word "commodore", stopping at the letter "m", so the buffer end looks like "com". You must enter "m" again, to preserve that last displayed character. If you review ALL the text, then you will be placed into edit mode at the end of the review. This allows you to continue messages that you have previously left off earlier. If you want to do formal text editing, use a wordpro, or the edit link. When using disk i/o with the buffer, note the bytes free counter at the bottom. Change Terminal Settings (C= C) ------------------------------- Although only 15 options are displayed here, the parameter file DT4.SETUP will actually save 80 bytes of data to disk. First, the 15 shown with C= C. Modem File. This is the name of the file you want to use to control the autodial, answer, off-hook, and on-hook routines. All modem modules must be created at the expense of you, he user. You must have some experience with assembler/ml to create one. I myself have only provided ones for the 1650 and 1670, and even these may not suit your tastes. When you enter the name of the new file, save the parameters back. The modem file will NOT boot up. You will have to re-boot to initialize the term for a new modem file. Function Key File. For the 16 function keys in the term, F1-F8, and C=1-C=8, you may load any default key file you want off disk. This file will be loaded up when you re-boot next time, or every time you hit RUN/STOP - RESTORE (Note: Run/Stop Restore will reset the terminal program in case of lock-up, but it will not be a complete reset that loads all the default files back in). Function keys are sent via terminal mode, color or ascii. You must be in command mode to send a function key string. You may use AT commands in the function keys if you have a smart modem. Key strings will be sent on a delay factor like buffer xmit. Also, you may not send a key string if the buffer is open, or you are xmitting the buffer. If you do not want to use a function key file, just use any file name that won't appear on the disk. Character Set. This will be the name of the default character set to load at boot up time. Using the name "rom" will set the characters to the normal text display you see, and will not load any custom character sets. Protocol. V4.0 uses both Punter and Xmodem. The xmodem is automatic, meaning that a CIS .IMG header will be stripped off the first block if found, and any padding on the last block will be stripped off before it is written to the disk This version was written by me, with the exception of the double buffering, which was found in a P.D. Merlin Source file of Xmodem 6.0, by MicroTechnic Solutions. Xmodem will operate in both CRC and Xmodem. When receieving a file, the term MAY be in CRC or SUM despite the setting, depending on what mode the sender is using. when sending, the setting here determines the mode. The Punter protocol is the new 8 bit C1.v2 version written by Steve Punter. I have made slight mods to it to accomodate relocation, on screen buffering, and my unique multi-transfer system. When setting the protocol, the files DT4.PROTO-P or DT4.PROTO-X will be loaded from disk. Be sure it is on the current disk! Once you set the protocol, it will be used as the default when re-booting, provided you save the setup back. Phone Directory Pages. V4.0 uses a variable length phone directory. Each page will reduce the buffer size by 800 bytes. Each time you change the value here, the buffer will be cleared, and reset, thus erasing all previous data, including a previous phone directory. Each page contains 20 numbers. The number of pages range from 0 (no directory) to 10, which gives a full 200 number phone directory. This cuts the buffer down 25%, but still leaves ample room. Block Size. This is for the Punter protocol only. Values can be from 40 to 255, which is the maximum. This value is the number of disk file bytes (+header info) to send for each block. Thus smaller block sizes mean more blocks to send. Time. Your standard 12 hour Am/Pm clock. When you want to change it however, you MUST enter 4 digits only. This will be an hour-minute (HHMM) militairy time value. ie., midnight is "0000", noon is "1200", 3 pm is "1500", and 9 am is "0900". Printer Device #. Values from 4 to 7 are ok. Printer Secondary Address. Values from 0 to 99 are ok. 0 is upper/case graphics, 7 is upper/lower case mode on a CBM printer. Disk Device #. Upon bootup, it is the device # of the drive you loaded the program from. Values from 0 to 99 are ok, but not recommended. Keyclick & Bell Tone. Since both have the same type of input, I'll explain both at the same time. The first character is an "E" for enabled, or a "d" for disabled. Use lower case "e" or "d" as the first input character, The second character is the waveform, either T (Triangle), S (Sawtooth) or N (Noise). No Pulse Waveforms as I didn't want to deal with pulse width. Use T, S, or N as input. The last 3 bytes are the frequency high byte, which has a range from 0-255. Example inputs: "ET80", "DN000", "ES145", etc. Dial Speed Delay. This is the number of MilliSeconds to delay between pulses with the 1650 modem when autodialing. 10 pps would work out to a delay of 1000/10 or 100 Milli- Seconds. 20 pps, the default, would be 1000/20, or 50 for a delay factor. Ranges can be from 0-999. With the 1670 module, a delay of 0 will TONE dial the modem, and any non-zero value will pulse dial the modem. If you write your own modem module, you will not need this value, or the next 2. Carrier Wait Delay. Because of line noise, long distance connect delays, etc., the 1650 modem will not look for a carrier until after this amount of time has elapsed. Hangup Delay. Before the start of each 1650 autodial, the modem is put on hook for this amount of time to ensure that the phone has been hung up. Both this and the above value can range from 0 to 99 seconds. When saving the SETUP file back, the following info will be used as the defaults for the term whenever you re-boot: -Modem File -Function Key File -Character Set File -Protocol -Phone Directory Pages -Printer Device & Secondary Address -Key Click Status -Bell Tone Status -Pulse Dial Delay -Hangup And Carrier Detect Delays -Current Screen Colors -Command Mode Status (En/Dis-Abled) -ASCII Or Color Mode -Upper Case Lock -Word Wrap Enable -Line Feed Status -Number Of Nulls -Transmit Delay -Baud Rate -Stop Bits, Word Length, Parity -Buffer Speed Flag -Carrier Detect Flag Disk Commands (C= D) -------------------- Before and after every disk access, the command channel is checked for disk errors. The error channel status will be displayed at the bottom status line. Enter all commands in the normal disk command style: n0:file name - soft new n0:file name,id - hard new s0:file name,file name,etc - scratch r0:new name=0:old name - rename c0:new file=old file,old file2,etc - copy/concatenate i0 - initialize v0 - validate u; - reset drive Use "$" to read the disk directory, SPACE to pause, and STOP to abort. $pattern, ie., "$dt4*" will read the directory according to dos pattern matching. File Options (C= F) ------------------- <R> Read A File. <P> Print A File (Ascii Or Normal). <E> Edit A File. <X> Extract From File. <T> Transmit File Over Modem. When transmitting a file (or buffer), it will be sent as ascii or color (normal) depending on whether you are in color terminal mode, or ascii. Transmit follows the delay factor like buffer xmit. Use SPACE to pause, and STOP to abort. The file will be displayed regardless of duplex, as all characters received from the modem will be discarded during the transmit. Extracting a file involves 2 passes. You will take a source file, and scan it on the first pass, to locate the line range you want (There is no provision for simultaneous extracts). When you have the desired line range, you will extract it to the destination file. You may use SPACE to pause pass 1 (Scan), and STOP to abort to pass 2. During pass 2, the source file will be scanned for the range, and then written out to disk. I have provided device 8 to 8 and device 8 to 9 extracts (NOTE: Source device is always 8, no matter what the terminal settings say). Using device 8 to 9 gives very fast results. You may abort pass 2 with the STOP key. When you want to Edit a file, you must load in the edit link file (DT4.EDLINK). Once loaded, the text editor will run by itself. This editor is very simple, and is not designed for professional formatted output; I put it in for the use of making pre-written messages to send to BBS's. It is slightly different then the version that was in V3.0. When reading a file, use SPACE to pause, and STOP to abort. When printing a file, use STOP to abort. fp EditLink Commands ----------------- Use the F7 key to select any of the following functions: <A> Append buffer to file. <C> Toggle caps lock. <D> Disk directory. <E> Erase lines from current position. <L> Load file to buffer. <M> Merge file with buffer. <P> Print buffer (sec addr = 7!). <S> Save buffer to file. <X> Exit back to DarkTerm 4.0. <$> Send DOS command. <#> Change drive device #. <+> Insert Line. <-> Delete Line. Cursor Up will fast scroll up. Cursor Down will fast scroll down. You may only work with SEQ files. The buffer capacity is 680 lines. Cursor keys will scroll thru the range of the buffer. Insert and DELETE will ONLY work with the current line, as does delete. Use a wordpro for better line control. This is a 40 column editor. Home will move to line 0. Clear will move to the last line. The current work line is always fixed and highlighted in the middle of the screen. The buffer will scroll through this line. Use F1, F3, and F5 to change the 3 text colors. Use F2 and F4 for the border and background colors. NOTE: the edit link resides at the start of the buffer; all data in the buffer will be cleared. Also, any current phone directory will be removed. Alter Function Keys (C= K) -------------------------- Each of the 16 function key strings can be up to 31 characters + an optional carriage return. enter the key you want to change for editing any of them. Use that key (F1-8, C= 1-8) when in terminal mode & command mode to send the key string. AT commands may be sent in this way. Function key strings use the same transmit delay as buffer and file xmit do. Load Character Set (C= L) ------------------------- Any character set may be used, but it must havee a load address of 53744 ($E000). I recommend a full, 512 character bank, since the CBBS-3 uses both sets simultaneously. If you use "rom" as the file name, you will get the standard ROM character bank. You must still set the character set file name with C= C if you want to make this set the default. Modem Setting (C= M) -------------------- You will see the status line change to the modem status line: B:0300 1:8:N B:C:D:0:050:NONE:-------- 1 2 3 4 5 6 7 8 9 0 A 1:Baud Rate. 200-600, 1200, or 2400 (NOTE: V 3.0 had a 1200 baud timing bug that was corrected here). 2:Stop Bits (1 or 2). 3:Word Length (5-8). 4:Parity (None,Odd,Even,Mark,Space). 5:Buffer Speed Flag (Inversed = full speed). When using <R> in the buffer options to review the buffer, the speed at which the buffer is displayed is determined by this flag. The buffer will be displayed at either full speed, or the speed at which the current baud rate is set at. Using "S" during the buffer read will toggle this flag as well. 6:Carrier Detect Flag. When enabled, no file transfers will occur without a carrier, and, if a carrier is lost during a file transfer, the transfer will be aborted, and you will be notified of the loss of carrier. 7:Duplex. Full duplex is the normal BBS-terminal operation mode. When inversed, you will be in half duplex, and all data is echoed back to the screen. 8:Nulls. After each carriage return, a number of nulls (Ascii 0) will be sent over the modem to slow down transmission to the system you are connected to. Values run from none to 9. 9:Transmit Delay. When sending a buffer, function key, or file over the modem, the host may not be able to receive the data as fast as you send it. So, you should use a delay factor to insert a pause between each character as it is sent. If you intend to buffer messages to a CBBS-3, use a xmit delay between 50-200, although in some cases, 0 might work. This delay time is in MilliSeconds per each character. 0:Linefeed Status: IN:All linefeeds (ascii 10) received will be converted to carriage returns. OUT:All carriage returns sent will be converted to line feeds when they occur. Note that this is not the same as adding a line feed after a carriage return. BOTH: Both of the above. NONE: No line feeds will be checked for A:When you go on-hook, or off-hook, the message will be displayed here. To Change: Use: Baud Rate B Stop Bits S Word Length W Parity P Buffer Speed Rate R Carrier Detect Flag C Duplex D Nulls N Transmit Delay T Linefeed Status L Off-Hook (On-Line) + On-Hook (Off-Line) - Phone Directory (C= P) ---------------------- V4.0 has a multi-dial, multi-page phone directory. This phone directory has the following characteristics: -1 to 10 pages, each containing 20 numbers, including a 20 character description, and an 18 character number string. -When loading or saving a phone directory, the file format is SEQ, and is a 40 column standard text file. You may thus edit this file with any standard text editor, including the edit link, if you do not want to use the <E>dit option. -When using the phone book, you must make sure that you have enough pages allocated for the size directory you will want to load in. -Up to 32 numbers may be dialed at one time, in the order that they are chosen with the (G)et command. After all numbers have been dialed once, they will be re-dialed until you enter STOP to abort auto-dialing. -The 18 character input string is exactly the same as that with the C= A command, and will use the same auto dial routine. Directory Commands: P:0 - Current Page # S:00 - Total numbers selected for dialing. <C> Clear all selected numbers. <D> Begin the multi-dial sequence. Note that T:000 is the try counter, and N:..... is the current number. <E> Edit numbers on current page. Use the cursor up/down keys to highlight the # you want to edit, then hit return. You will then have to enter a number, and a description. Hit return to select more numbers on the current page. Use STOP to exit the edit option. <G> Get Numbers. Select the numbers you want to dial like you did with <E>. Start at the numbers you want to dial first, then continue up to 32. If you want to remove a number if it is selected, then just hit return at it's position, and the number will be removed from the selected list. When a number is selected, an asterisk will appear between the number and description. <L> Load directory file. <N> Dial a single number (Same as dialing using C= A). (S) Save current directory. (+) Increment page. (-) Decrement page. Reset Clock / Timer (C= R) -------------------------- Very simple, eh? Set Screen Colors (C= S) ------------------------ This one is simple too, just use the number keys, 1-3. File Transfer Options (C= T) ---------------------------- <1> Single File Upload. <2> Single File Download. <3> Multi File Upload. <4> Multi File Download. NOTE: The multi transfer modes are designed and built into the Punter protocol, and will NOT work with Xmodem, so remember to change the protocol to Punter when multi-transferring. The file status line will appear as follows: P:FILE NAME:123:SU:B-0000:F-000 1 2 3 4 5 6 1:File Type. 2:File Name. 3:File Size. 4:Transfer Mode: SU:Single Upload SD:Single Download MU:Multi Upload MD:Multi Download 5:Blocks Left (Multi Only). 6:Files Left (Multi Only). Use the STOP key to abort any file transfer. Xmodem protocol was explained before. The multi-file transfer mode is unique, and guaranteed to work error free. It will not work with any other term. Source code for the multi-transfer method is available on request. Exit Program (C= X) ------------------- Very simple too, will exit to BASIC. Command Mode Summary (C= Z) --------------------------- Gives a color file of all commands in command mode (DT4.HELPME). The last few commands are: C= * (Clear the buffer), C= \ (Pound) (Send ASCII delete (127)), and CTRL ; (Send ESCape). The remainder of the docs explain how to create a modem module, which will be followed by info on the DarkStar BBS Systems-3. Creating A Modem File --------------------- A modem file is a small machine language file that handles 4 basic modem communications routines: 1. Auto-Dial - $4600 2. Auto-Answer - $4603 3. Off-Hook - $4606 4. On Hook - $4609 You should use an assembler to create a modem file, and you must follow certain guidelines and restrictions when making one. I have provided PAL source code for both the 1650 and 1670 modem files, and I have also supplied an equates file of the entire terminal program, to indicate what the terminal program uses, and what it doesn't. The file may not go past $4A00, therefore, you have up to 1K of space to create the file. You may access any one of 10 routines used by DarkTerm, found in a jump table at $0900. The 10 routines are: $0900 - Print current character in accumulator. This is not $FFD2, but the routine that prints to the custom split screen thru my screen editor. $0903 - Print a line of text. Like above, but will print the string past the JSR call. Use .byt 0 to end the string. JSR $0903 .ASC "This is a text string." .BYT 0 more stuff.... $0906 - Works like $0903, but will print up to 40 characters to the status line. JSR $0906 .ASC "This appears on row 24" .BYT 0 more stuff.... $0909 - Hex to decimal conversion routine. Enter with .X = lo byte, .Y = hi byte. Exits with DECML (34-39) containing the decimal string, in REVERSED order. $090C - Milli Second delay timer. Enter with .X = milli seconds lo byte, .Y = milli seconds hi byte. .A will be lost. $090F - Jiffy delay. Enter with .A containing from 1 to 255 jiffies (1/60 second). $0912 - Screen Input Routine. Enter with .A = # bytes to input/clear, .X = row, and .Y = column. Returns with length of input in .A, and the data in the input buffer @ 60 decimal. $0915 - Find file routine. Enter with .X/.Y = low/hi byte pointers to a file name of length 16, padded with shifted spaces. Carry will be cleared if not found, set if found, .A = type, .X/.Y = file size. $0918 - Hex to decimal 2 byte converter. This converts any hex digit from 0 to 99 in .A. Returns with .x as the first digit, and .Y as the second digit. $091B - Evaluate Integer. Will take a 1 to 5 character digit string in the input buffer at 60 dec, and convert it to hex. Enter with the input buffer and input length (15 dec) set, and call this routine. Returns with carry clear if it wouldn't evaluate, carry set if it was ok, .x/.y = lo/hi bytes of integer string. The modem file must start at $4600, and you must create a jump table at $4600, such as: *=$4600 jmp autodial jmp answer jmp off-hook jmp on-hook Autodialing. .X and .Y contain the lo/hi byte pointers to the 18 character dialing text string. See the source for 1650 and 1670 codes for how to break it down. You may use the upper 60 bytes of the input buffer as zero page use (80-140). Return with: Carry Clear is STOP key was hit to abort dialing. Carry set, AND: Zero flag set (BEQ) if the autodial was successful, and a carrier was detected. Zero flag clear (BNE) if the autodial did not give a carrier. Auto-answer. Exit with carry clear if STOP was hit, or carry set if carrier is detected. Off-hook, and on-hook, should be done and just use an RTS. No special requirements here. Please consult the source code for more info. Note that you can ignore the pulse delay @ 878/9 dec, the carrier wait delay @ 880, and the hangup delay @ 881 dec. I just used it in the original code, and it's use is not needed in your own routines. Info On DarkTerm 4 / DarkStar BBS-3 ----------------------------------- This terminal program was written and debugged over a 3 week period. Much of the basic i/o routines were taken from V3, but much has been changed. I am sure that all the minor irritations I have received about V1/2/3 have been resolved, and I suggest you only use this version. I know that the lack of easy help menus may affect ease of use, but I needed the space, and I found large menus to be real memory gobblers. I may add an auto-mode overlay later on, but it will not require any changes to the current program if I do make the changes. DarkTerm V4.0 Memory Map: ------------------------- $0400-$05FF - Function key storage $0600-$07FF - Variable storage $0800-$3EE1 - Main code $3EE2-$45FF - Punter/Xmodem Protcol Overlay Area $4600-$49FF - Modem file overlay area $4A00-$4BFF - RS232 Buffers $4C00-$CBFF - 32k Buffer $4C00-$5E00 - Edit Link Overlay $4C00-$XXXX - Phone directory storage $4C00-$XXXX - Auto-Mode expansion $CC00-$CFFF - Screen memory $E000-$EFFF - Custom character storage $F000-$F7FF - Screen swapping area $F800-$FFFF - Not Used DarkStar BBS V3.0 ----------------- These are actually 2 BBS programs in 1, a full color BBS program, and an ascii BBS. Each are basically identical, and offer many features. It is a user definable system, and is far too in-depth to explain.
