Lederman" 34 lines 4-APR-1989 11:01 -< Working! >- -------------------------------------------------------------------------------- I have them working dial-in/dial-out. The problem turned out to be modem control signals (no surprise) which I found when I finally got a break-out box. The important settings were: ATS0=2 (to allow dial-in as well as dial-out) AT\J0 (so the VAX is always 2400 baud regardless of line speed) AT\Q1 (flow control on the serial line, may not be vital) AT&D0 (ignore DTR, so the modem will respond when you send commands to it even if the VAX thinks the modem is off-line) AT&C1 (Carrier detect follows the remote system. Otherwise, the VAX thinks the modem is always connected to something even if it isn't.) AT\D2 (DSR and RTS follow CD: this one is important. If it's set to AT\D1 the modem will raise one of the signals when you give it a dial command, and in 30 seconds the VAX will hang you up unless the other signals have come up. With AT\D2, none of the modem control signals come up until CD (carrier) come up). The last three did the trick. Now I can dial out (manually or with VAXNET) and dial in. The modems always run at 2400 baud between the modem and the VAX and auto-speed to the remote system.
