From: Rick Conn <rconn@brl> UMODEM supports three protocols, but the one of most general interest is the Christensen protocol (FTP 3). Very good doc is in the CPM ARs on MIT-MC on it. M2PROTO.DOC or some such (M2PROTO is too long) is what to look for, and it is either in CPM, the MODEM2 AR, or the MODEM7 AR. Rick
