- It's been years (umm, the better part of a decade) since I used any form of
- Procomm, but I have never failed to make any decent modem with NVRAM work with
- any decent terminal software using the following procedure:
-
- Geoff's Modem Setup Checklist:
- ------------------------------
-
- Given manuals that translate these items into modem and communications
- software settings, you should be able to get reliable, if not optimum,
- results:
-
- * Disable auto-answer (usually the command for this is "ATS0=0") so
- that your modem won't answer incoming calls from friends
- whenever your computer just happens to be on.
-
- * Disable DCD override (usually the command for this is "AT&C1") so
- that your communications software can use the carrier detect
- line to determine whether it is still connected.
-
- * Disable DTR override (usually the command for this is "AT&D2") so
- that your modem will obey DTR signals from your communications
- software to hang up or not answer an incoming call.
-
- * Disable the escape character, usually by setting S2 to a value
- higher than 127.
-
- * Make sure that your serial cable supports DB-25 pins 4 (RTS) and 5
- (CTS).
-
- * Enable RTS/CTS handshaking in both your modem and your
- communications software to prevent data loss when buffers
- fill. Disable XON/XOFF handshaking in your modem to prevent
- corruption of binary data streams. You may wish to leave
- XON/XOFF handshaking enabled on the communications software at
- either end for end-to-end signalling. This normally does not
- corrupt binary data streams because most communications
- programs disable XON/XOFF flow control during binary
- transfers; equipment along the way cannot do this.
-
- * 'Lock' your modem's DTE speed (i.e., fix it so that the modem
- doesn't change the speed of its RS-232 port when it connects).
- Set your communications program to do the same (usually by
- ignoring the number which follows the word "CONNECT"). Some
- modems can be configured to switch the DTE speed if the
- connection does not include an error correctioon protocol, in
- which case a higher DTE speed is not always useful. If your
- modem can do this, and if it reports connects using the three-
- line "CONNECT 19200", "PROTOCOL: LAP-M", "CARRIER: 9600"
- format, you may wish to enable this and set your
- communications software to obey the DTE speed switches
- dictated by the modem.
-
- * Write this configuration to your modem's nonvolatile memory (usually
- using the "AT&W" command). This will make the current
- settings default following a reset, and the 'init string' for
- any software confgured according to this document is... "ATZ"!
- Please note that the current serial port speed may also be
- stored, so the speed at which you issue the "AT&W" command
- should be the speed at which your software will use the modem.
-
- Obviously, there are exceptions... but this is a good procedure for anyone who
- doesn't yet know enough to be worried about the exceptions.
