- Users
- -----
-
- For someone to be able to use the modem port, you MUST have given them a
- password. Do an EU and use W to set the password. The user can change
- it using the NP command over the modem port.
-
- Modem Settings
- --------------
-
- The default settings are: 'T E0 V1 X1 Q0 S7=60 S0=0'
-
- Do not change E0, Q0, V1, X1, or S0. All other settings are fair game.
- You can make any changes automatic by putting them in the
- INITIALIZE_FILE (see PARMS.DOC)
-
- Modem switches
- --------------
-
- You should set your modem to hangup and enter command mode when DTR goes
- low. On older modems, this is a hardware switch. On newer modems, it
- is a software switch (ATSxx=y type).
-
- Some users have reported intermittent crashes during initialization with
- certain modems. A suggested fix is to
-
- ECHO AT&C1&D2 > COMx
-
- before bringing up the BBS. The above line can be put in a BAT file.
- Substitute a real com number for the "x" above. This fix will only work
- with COM1 and COM2.
-
- User settings
- -------------
-
- Recommended user setting for their terminal programs are:
-
- - Half duplex or Echo on -- Program must supply echo of what is being
- typed.
-
- Forwarding
- ----------
-
- A typical forwarding script might be:
-
-
- PATH AA6 B AA4RE
- CT*70,8483865
- R*call sign*
- SAA4RE
- R*password
- SMYPASS
-
- Note that this represents a change from previous versions. The CONNECT
- message is now taken care of by the code. The system will also change
- speed based on the connect message.
-
- High speed modems
- -----------------
-
- I have test the BBS with a Telebit T2500 9600bps V.32, V.42bis modem
- with good results. Pointers are:
-
- 1) I locked the speed of the interface between the modem and the
- computer. I also set the "lock_modem_speed" variable to yes in
- PARMS.BB. This allows the modem to make whatever speed changes it wants
- without have to keep resetting the speed in the BBS.
-
- 2) If you have an modem with error recovery or with compression, you
- will probably need to set HARDWARE HANDSHAKING on in MBBIOS for the
- modem port. See MBBIOS documentation on how to do this. Hint: Its an
- item on port definition panel.
-
- 3) When connecting to a Non-MNP modem, an MNP modem will try to
- negotiate an MNP session. This shows a garbage characters sent to the
- distant (non-MNP) end. You may have to change your forwarding scripts
- to handle this. Usually you can fix this by adding the following after
- the connect line:
-
- R*
- S
-
- Remember that all 9600 bps modems are not created equal. There are
- multiple implementations and none of them work with each other. The two
- most popular are HST and V.32. V.32 is a CCITT standard for 9600 bps.
-
- *** Warning *** Slow computers and some fast ones will get overruns at
- 9600 bps. An overrun is when the line is delivering data to the
- computer faster than the computer can handle. This can be helped by
- acquiring a serial port or modem card that has a 16550A chip in it
- rather than the 8250 or 16450. The 16550A is plug compatible with the
- older chips and includes a 16-byte buffer. You can purchase them for
- about $10.
-
- Cabling
- -------
-
- The following control lines are used on the modem cable: RTS, CTS, DCD,
- DTR, DSR. Your RS-232 cable must have all of these.
