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.
