Issue AT &Q(0,5-9) &W from a Synchronous Terminal to restore the modem to Asynchronous Mode. 2. Connect modem to an Asynchronous Terminal with the DTR signal (line 20) disabled (a "break-out" box works very nicely for this) and issue the configuration you want or AT &Q(0,5-9) &W to return the modem to Asynchronous Mode. | |
