Leased line with the V42bis (Non-v32modems) after the AT&L1 to set leased line mode, you need A:>2 people to make the connection, OR B:> a ring-down (voice) leased line. A:> One person types ATX1D (which tells the modem to 'dial' without looking for a dial tone) in terminal mode, the person on the other end types ATA (which tells the modem to pick up the line and answer). B:> With a ring-down line, the modem (or Phone) will ring on the other end when one end is taken off-hook. So if the modem is set with ATS0=1 (autoanswer), then the person originating can type the ATX1D which will put the modem off hook (and in originate mode) and the other end gets a RING and will answer.
