How can i program two modems for when one HANGS UP, an automatic connection be estabilish? I want to connected two modems directly one with other, in a NODIALTONE line. Today, i have 2 modems: A B For a connection, i have to type ATA on B modem, and ATX3 on A modem. The problem is that the machine that i will connect on modem B only wait for a CONNECTION status, nothing more, the machine can't send a ATA command to MODEM B. Thanks again!
