Greetings to all. I have recently aquired a new modem, and have no information regarding it, and wonder if someone somewhere knows anything about it. The modem is a Multi-Tech Systems modem FM-327. It has two ports on the back: a 'regular' db-25 RS-232C connector, and a db-15 connector. The 15 pin connector throws me for a loop. Theres a cable that plugs into it that has what looks like a regular RJ-11 phone line plug on the other end. So it looks like the db-15 to the phone line. Next, on the back panel, there are four switches. Power switch; one marked 'half', assuming half-dup; one marked 'OOS', no idea; and one marked 'test', assuming a local loop-back There are a varity of LEDs on the front panel: RCV and XMT; DTR, DSR, RTS and CTS, and OH. Those I can understand. Other LEDs: OOS, RI and CO. An inspection of the interior of the modem reveals standard TTL logic chips, power supply, and nessarary buffers (1488 1489 et al). No 'intelligence' is found (eg, CPU and/or ROM). Plugged into the RS-232C port of my computer (for the record, a Xerox 820-II) doesnt reveal anything at all. I transmit data from the computer to the RS-232C port, which isnt recived by the modem. In effect, the modem is dead. I realize that this isnt your standard run-of-the-mill Hayes AT compatable modem, and would like to know if this can be used on a micro (stated above, async port). Some other useful information: this was at one time connected to the comm ports (and FEP) of a Data General Eclipse/8000 mainframe. This -may- be a limited distance modem, leased-line only. I have the feeling that it may communicate up to 9.6k baud. Any information would be greatly appreciated.

Well, after a call to Multi-Tech, I found out that what you have is an old dial modem. Speed (watch out!) 300 Bps. >Plugged into the RS-232C port of my computer (for the record, a Xerox >820-II) doesnt reveal anything at all.

Make sure your machine is set to 300 Bps async and try it again. They said that it used the Standard Hayes command set. You might try CAPS, as the Hayes modems that I've used wouldn't accept a lower-case "at". (has that changed?) One other thing, A modem that old may require a DAA (Data Access Arrangement) between the modem and the phone line. That's if you even condsider using the beast.
