I have a clunky UDS 212LP modem sitting around that I would like to use as an inbound modem on my system, zorch. Does anyone out there know anything about these beasties? It has three switches, ORG/ANS, 300/1200 and on the front TALK/DATA. If I set it to ANS, 1200 and TALK, it never picks up the line. If I switch it from TALK to DATA, it picks up the line immediately. This doesn't work real well as an auto-answer modem; maybe it's just plain not possible. However, if there is anyone out there who knows some trick, e.g., toggle DTR low, please let me know.

We used to have a few 212LP's around here (they are proably still in service somewhere). It was a nice modem for its day. Fit nicely under a desk phone. Fairly cheap compared to what else was on the market at the time. And needed no electrical connection (it was powered by the phone line, hence the LP in the name). Unfortunatly, it couldn't do auto answer. I think the fundemental problem was that to be line powered, you are *very* limited in how much current you can draw from the phone line. They probably couldn't power the auto-answer circuitry and stay within the power limits. -- Roy Smith, Public Health Research Institute 455 First Avenue, New York, NY 10016 {allegra,philabs,cmcl2,rutgers,hombre}!phri!roy -or- roy@alanine.phri.nyu.edu "The connector is the network"
