I can only tell you about Hayes modems, but it's possible that Everex behaves the same way. The symptom of the MR light blinking while online and "locking up" the modem happens when the modem THINKS it has seen a "Remote Digital Loopback Request" from the other modem. This request is a particular signal pattern, and it is POSSIBLE for line noise to cause the modem to think it has seen this signal. The modem thus enters Remote Loopback state, which is indicated by the light blinking. Since 99.99% of users NEVER intentionally want to be in Remote Loopback state, the best thing to do is to disable granting of remote loopback requests. This is accomplished by the &T5 command, which can be written to non-volatile memory. But the &F factory default is &T4, so if you have programs that force an &F to the modem, you'll need to include an &T5 in those initialization strings to keep granting of remote loopback requests disabled. AT&T5&W is always one of the first things I do to a new modem out of the box! -- Toby -- Toby Nixon, Principal Engineer | Voice +1-404-840-9200 Telex 151243420 Hayes Microcomputer Products Inc. | Fax +1-404-447-0178 CIS 70271,404 P.O.
