DTR --- at&d0 - ignores DTR line from computer at&d1 - goto AT command state on DTR on->off change, (no hangup) at&d2 - modem resets itself on DTR on->off change ------------------------------- --- FLOW CONTROL ------------------------------- XON/XOFF FLOW CONTROL --------------------- at&k0 - disable local flow control at&k1 - ? at&k2 - ? at&k3 - RTS/CTS bi-directional hardware flow control at&k4 - XON/XOFF bidirectional software flow control at&k5 - uni-directional XON/XOFF flow control ------------------------------- --- AUTO ANSWER ------------------------------- ats0=0 - no auto answer ats0=1 - auto-answer on first ring ------------------------------- --- CARRIER ------------------------------- ats7=30 - time to wait for carrier detect before giving up ats9=6 - recognize carrier by .6 seconds of carrier tone ats10=10 - hangup after 1 second without carrier tone S REGISTERS ----------- ats0=0 - no auto answer ats0=1 - auto-answer on first ring ats7=30 - time to wait for carrier detect before giving up ats9=6 - recognize carrier by .6 seconds of carrier tone ats10=10 - hangup after 1 second without carrier tone ats11=75 - speed of tone dialing (in miliseconds. minimum 50) DIAL MODIFIERS -------------- , - pause for 2 seconds (value of S7 register) ; - return to command state after dialing ! - flash the hook for 1/2 second R - reverse to 'answer' mode after dial (@ end of tele#) W - wait up to 30 secs for 1 sec continuous dial tone @ - modem waits 30 secs for one or more ringbacks RECOMMENDED SETTINGS FOR UNIX DIALUP MODEM WITH UUGETTY ---------------------------------- at&f - return to factory settings ats0=1 - auto answer on first ring ats2=127 - disable +++ escape (allows binary file xmission) atl3 - loud spkr volume atm1 - spkr on until carrier detect ate0 - echo off atq1 - no messages at&c1 - DCD active on carrier detect, inactive on hangup at&d2 - modem resets when DTR dropped at&s1 - DSR active (when??) at&k0 - disable XON/XOFF flow control at&r0 - ignore RTS in cmd mode, CTS follows RTS in data mode at&w - save these settings FOR UNIX DIALOUT ---------------- at&f ats0=1 - auto answer on first ring ats2=127 - disable +++ escape (allows binary file xmission) atl3 - loud spkr volume atm1 - spkr on until carrier detect ate1 - echo on atq0v1 - disable quiet/enable verbose messages at&c1 - DCD active on carrier detect, inactive on hangup at&s1 - DSR active (when??) at&d2 - modem resets when DTR dropped at&k0 - disable XON/XOFF flow control at&r0 - ignore RTS in cmd mode, CTS follows RTS in data mode at&w - save these settings SEE ALSO www.hayes.com - I think they have all models of modem settings available online.
