Most PC modems are configured that way by default. If DSR is always on, VMS will continually cycle DTR trying to get the modem to hang up the phone. The modem needs to assert DSR only whne it has gone off-hook. -- -------------------------+----------------------------------------------- Roger Ivie | "Inside every PC-DOS system is a powerful, ivie@cc.usu.edu | flexible MS-DOS system just waiting to be http://cc.usu.edu/~ivie/ | set free" -- Mike Higgins | Computer Language magazine, 3/85
