It is generally a mistake to use "smart modems" for what are strictly dial-in lines. There are just too many ways for them to get confused a lock out incoming calls. I would just use the basic dumb modems from a reputable manufacturer, or maybe a smart modem that has a physical switch/jumper to disable command mode. We have some dumb modems, some Racal Vadic VA212's which are smart but well behaved and a couple of USR Couriers. We use the Couriers for dial-in and uucp dial-out, and it seems that dialing out keeps them unwedged most of the time. -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
