Not sure what the correct term is for these devices but I have seen
"Modem Eliminator" on several. I'm not at all sure I am interested in
keeping all these things. I have about 4 to 6 or so of these Micom
units and probably a few others of some other brand. They look like they
have a serial port and telephone connections. They seem like they were
part of all the larger systems a number of years back and thus seem like
they might be worth saving. Anyone interested?
