- What is COM2COM?
-
- Com2Com is a remote communications package featuring full
- screen transfers, file transfers and remote/host printer
- control. Com2Com does not support graphics modes or mice.
- Most available commercial software that does not REQUIRE
- graphics or a mouse will run with Com2Com. We have tested it
- with the following programs:
-
- Professional Write
- PC-Write
- FoxBase,FoxPro,Clipper
- Quick Basic 4.01b
- Quick Pascal
- Skyline Property Mgmt.
- Great Plains Accounting
- SBT Accounting Programs (dBase III+)
- Novell Netware 2.15 SFT
-
- Some modems may not support the commands required by Com2Com.
- We have tested it with the following modems:
-
- Star 2400 (internal/external)
- Cardanal 2400 (internal/external)
- US Robotics Courier HST
- Watson (1200 & 2400)
- Avatex 1200 External
- Everex 2400 (internal/external)
-
- Please note that we tested only the US Robotics 9600 BPS
- protocol, NOT V.32 and NOT dual standard. We also had some
- problems getting the Watson modem to connect to the US
- Robotics, altho we eventually had some success.

- and modems.)
-
-
- THE DEFAULT PASSWORD IS 'URANAD' ! This is required to run the
- setup and installation programs.
-
-
- 1.0 Setting up COM2COM
-
- To install COM2COM simply copy all files associated with the
- system into a subdirectory on your hard drive, or copy them to
- a system floppy. They will fit on a single 360K diskette with
- no problem. The files included with COM2COM are:
-
- COM2COM ABS 4000 4-01-91
- SETUP ABS 4000 4-01-91
- COM2COM COM 10448 4-01-91
- CHOPS EXE 46480 4-01-91
- CLSPC EXE 5088 4-01-91
- FCOPY EXE 32896 4-01-91
- SETUP HLP 14560 4-01-91
-
- The setup program 'CHOPS' is used to change the user options for
- COM2COM.
-
- To invoke the setup program from COM2COM simply type 'CHOPS' at
- your DOS prompt and press [ENTER]:
-
- C:\USER>CHOPS
-
- The setup program is documented on-line, which means that help is
- available within the program by pressing F1.
-
- When CHOPS starts, you'll see a large window with the current
- setup options. And a flashing cursor to show you that it is
- waiting for you to select a COM Port.
-
- There are four radial dialog options (COM PORT, PRINTER PORT, BAUD
- RATE, and ALIAS) and 2 check boxes (REBOOT HOST, LOCK HOST)
-
- To change the radial options, use the arrow keys and the floating
- dot will move accordingly to show the current option for that
- Field.
-
- To move from field to field in the setup program press the TAB
- key, or SHIFT+TAB.
-
- To change check box options, press the space bar. An 'X'
- represents that item is checked.
-
- Holding down the ALT key highlights the shortcut keys to all
- options. To move directly to another field without TABbing through
- all the options before it, hold down the ALT key and press the
- letter associated with that field.
-
- The REBOOT HOST option will reboot the host machine upon
- connection termination. This may or may not work with your
- machine, it works on all of ours, but we've been around long
- enough to know that some BIOS stuff is really strange. If this
- DOESN'T work on your machine we would appreciate a postcard
- telling us that it failed, along with your brand of machine,
- version of DOS and type of BIOS (AMD, AMI, Phoenix, etc).
-
- The LOCK HOST option is not implemented in the shareware
- version.
-
- The printer return code is a hexadecimal number indicating the
- value that will be returned to the program doing the printing
- if the printing is successful. The default value here is 90H.
- If you have any remote printing problems you may have to
- change this number. Note that COM2COM will NOT detect paper
- out or other error conditions on REMOTE printers (printier
- attached to the calling computer).
-
- Press ALT+O to pull down the options menu, which allows you to save
- the configuration and exit.
-
-
- 1.1 What is a host and a remote computer?
-
- A host is a computer that is waiting for another computer (the
- remote) to connect to it via modem and establish a communications
- link. Once the two computers are connected, the host will ask for
- the user to login (discussed later) with a special password that
- only certain users are allowed to have.
-
- Once the user has correctly logged himself onto the host, the
- remote computer takes over the Hosts' keyboard, disk drives and
- printer; and the host takes over the remote's display. The
- remote has actually taken over the host so that a program that
- displays information will display the information to the remote's
- screen or printer (whichever is being addressed.) Likewise, any
- input to the program comes from the remote's keyboard.
-
-
- 1.2 Setting up a COM2COM host computer.
-
- So that both computers are speaking the same language, both
- computers will need a copy of the save version of COM2COM.
-
- To get the same version of COM2COM on 2 computers, simply make a
- copy of the current (latest) version to a floppy disk.
-
- Put a copy of COM2COM in drive a and close the drive door and
- type "A:" at the DOS Prompt. Your screen should look similar
- to the screen below. If you are running a floppy based
- system, the first prompt will be A:\> or similar.
-
- C:\>A:
- A:\>_
-
- ** Note: if you have a hard disk based system, you may want to
- copy COM2COM to a subdirectory of the hard disk and
- switch to that directory before continuing.
-
-
- To start COM2COM in host mode just type: COM2COM at the DOS
- prompt.
-
- NOTE: If you haven't setup your copy of COM2COM to be used as a
- host facility, you MUST do so before trying this.
-
- C:\USER>COM2COM
- COM2COM Version X.XXx (C) Copyright 199x Oaklandon Computer Research.
- COM2COM: Waiting For Connection..
- C\USER>_
-
- The host computer is now waiting for a remote computer to connect
- to it and establish a communications link.
-
- The host computer, once invoked with COM2COM has returned to its
- normal computing state, or back to the command mode. You can now
- run other programs or leave it waiting at the command prompt so a
- remote computer can enter commands (such as run applications, copy
- files, etc...)
-
-
- 1.3 Starting remote access.
-
- Once a "HOST" computer is waiting for a remote connection, any
- computer with a modem can dial into the host and establish a
- connection (Provided the host and remote are both using the same
- version of COM2COM.)
-
- NOTE: If you haven't setup your copy of COM2COM to be used as a
- remote facility, you must do so before trying this.
-
- To get the remote computer to dial into the host, you must start
- COM2COM in remote mode by typing:
-
- C:\USER>COM2COM
-
- You will then see a message displaying that the modem is being
- initialized and a few seconds later, a dialogue box asking for
- the phone number:
-
- +---------------------------------------------------------------+
- | COM2COM Version X.XXx (C) Copyright OCR.... All rights... |
- | |
- | Enter Host Computers' Phone number: |
- | [_ ] |
- | |
- +---------------------------------------------------------------+
- | <ESC=EXIT> <Enter=DIAL> <CTRL-X To Terminate Session> |
- +---------------------------------------------------------------+
-
- Entering in the phone number in the space provided will dial the
- host and establish a communications link that only COM2COM can
- understand. Dialing the host with any other terminal program will
- not work correctly.
-
- After the Host has correctly identified that the remote is using
- COM2COM, you will then see a prompt to enter your user id.
-
- CONNECT xx00 Baud.
- USER-ID: _
-
- The remote user will get 3 chances to correctly enter the user
- id that has been assigned by a supervisor. After accepted, the
- user will then see the same screen as shown by the host and can
- enter commands or keystrokes just like the remote computer and
- host were the same computer.
-
- 2.0 Controlling the printer.
-
- The host computer will default to its local printer when not
- connected to a remote (e.g. all printer output goes to the printer
- connected to the host provided it is available.)
-
- Once connected, the host computer defaults to the printer connected
- to the remote (e.g. all printer output goes directly to the printer
- at the remote end, provided it is available.)
-
-
- 2.1 Changing printer status.
-
- To change the default status of the printer (while a remote is
- connected) press ALT+P. You should see a box displaying the
- correct printer status:
-
- +-------------------------------+
- | |
- | Using Host Printer for output |
- | |
- +-------------------------------+
-
- ALT+P is a toggle, so the next time you press ALT+P you will change
- the default printer back to your printer.
-
- +-------------------------------+
- | |
- | Using Your Printer for output |
- | |
- +-------------------------------+
-
- 3.0 Terminating a communications session
-
- Press ALT+X to disconnect from the host at any time. Any print
- jobs will be lost (if directed to the remote printer) but
- processing jobs will continue until finished.
-
- +---------------------------------+
- | |
- | Disconnect from Host (Y/N)?_ |
- | |
- +---------------------------------+
-
- Press Y to disconnect and terminate the session. The remote will
- disconnect from the host and return to the operating system.
-
-
-
- 4.0 File Transfers
-
- File transfers are implemented as a separate program called
- 'fcopy.exe'. This program is run on the host computer like any
- other, except that it automatically detects the presence of the
- COM2COM communications engine and uses it to transfer files instead
- of screen and text information.
-
- To start FCOPY you must be at a DOS prompt on the host machine.
- From the DOS prompt simply type 'fcopy'. The devices in FCOPY are:
- SYS:REM/ referring to your 'local' machine
- SYS:HST/ referring to the host or 'called' machine
-
- A box will appear on the screen asking for 'FROM' and 'TO'. The
- default is FROM:SYS:HST/ and TO:SYS:REM/. Following these you may
- insert a fully qualified DOS path and filename. You may also
- backspace over the HST/ or REM/ to change the copy defaults. Once
- valid filenames are entered and the [ENTER] key is pressed the
- transfer begins, with a status window to show how much of the file
- has be transferred so far. Before pressing [ENTER] you may move
- from field to field using the TAB key and you may abort the copy
- operation by pressing [ESCAPE].
-
- 4.1 External Protocols
-
- If FCOPY won't do it for you, COM2COM also works with popular
- external protocol programs such as DSZ from Omen Technologies.
- To transfer files using an external protocol you must have the
- external protocol program on BOTH the host and remote
- machines. Run it with the correct command line on the host
- machine first, then shell to DOS on the remote machine and run
- it there FROM WITHIN THE SHELL.
-
-
- 5.0 Questions, Troubleshooting.
-
- Q: I start my computer as a remote and enter the number to dial,
- but it doesn't dial.
- A: Is the modem on?
- Are all connections to the modem secure? (ie Phone line, serial
- cable, etc...)
- Is your modem on COM 1 or COM 2? (use setup to change comports)
-
- Q: I hear the modem connect, but I don't see anything on my screen.
- What can I do?
- A: Make sure that you have used the correct modem set up as
- described in the set up section of this manual. Failing that,
- try pressing [ENTER] on your machine and see if that brings us
- the 'USER-ID:' prompt. Make sure that the host machine is indeed
- running COM2COM and not some terminal program or other remote
- control package. If all else fails, give us a call (If
- you're a registered user).
-
- Q: When I get connected and enter my password, the screen goes
- blank, usually completely white. What's happening?
- A: You have probably dialed into the host computer when it was
- running a graphics application. COM2COM does not currently
- support graphics.
-
- Q: My modem does some crazy things when I try to dial out, and I
- often can't get anything to happen at all. What's wrong?
- A: Be sure that your modem setup strings are valid for your
- particular modem. Refer to your modem manual if necessary and
- setup the strings using the setup program (CHangeOPtions or
- CHOPS) to the proper values for your modem.
-
- Q: After using COM2COM I can't get my other terminal programs
- (such as Procomm, PCPLUS or Telix) to work correctly.
- What's going on?
- A: Currently COM2COM does NOT reset the modem after exiting.
- So the modem will still be set up for COM2COM. In Procomm
- or Telix you need to make sure that your initialization
- string is complete (i.e. turn auto answer off, set results
- to character). You will need to check your modem manual
- for complete instructions on how to do this. If you are
- using host mode and are NOT restarting COM2COM after a
- reboot you might want to reset the modem to turn off auto
- answer in your autoexec.bat file. Again, see your modem
- manual for details.
-
- Q: Somethimes after I clear the screen on the host there are
- still characters left on my screen in odd places. What's
- wrong?
- A: COM2COM can get confused about what it's supposed to send,
- either because of phone line noise or because of the way some
- programs clear the screen. COM2COM only sends what's updated
- on the screen, so if it misses one byte, that byte will remain
- there until changed. This is a hanging character.There is a
- program included with COM2COM called CLSPC that fills the
- screen with spaces. If you have hanging characters and they
- really bother you, run this program on the host. No more
- hanging characters!
- One way that we have found to reduce phone line noise is to
- use an external modem. Some internal models tend to pick up
- noise for the PC's power supply.
- By the way, the registered version includes screen transfer
- error correction....which obviates the need for CLSPC!
