I have recently acquired what looks like a modem. It
has the FCC
certification for a modem and has a jack for voice equipment 8 conductor
multi-line. But when connected to my VT-220 it does not act like a
modem. No response to Hayes commands won't even give me a error
message.
To put it bluntly, not all modems are Hayes compatible. Especially
if the modem is answer-only or for some specialized application.
It is a Line Miser DOV 640 by Gandalf Data Limited.
The Gandalf equipment that I'm familiar with are communications
multiplexers - it's likely (especially given the "Line Miser" name)
that what you've got there is a synchronous modem intended to connect
to a terminal multiplexer. It may even be intended for applications over
leased lines (i.e. no dial tones).
