; An MS-DOS Kermit script program for dialing Telebit T3000 and similar
; modems (T1600 and QBlazer, possibly WorldBlazer), to be used with MS-DOS
; Kermit 3.11 or later. See T3000.DOC (MSMT3000.DOC) for documentation.

stop 1 Can't get modem's attention
; Telebit T3000 modem setup, should apply to all connections:
;
; X12 Result code selection, wait for dialtone, recognize busy signal.
; &D2 Disconnect call and return to command mode if DTR drops;
; this allows HANGUP to work if cable properly wired.
; S50=0 Automatic modulation speed determination.
; S94=1 Allow connection at any speed and allow modulation fallback.
; S58=2S68=255 Use RTS/CTS hardware flow control.
; S60=0 Data format: 8 data bits, no parity.
; S61=0S63=0 Pass BREAK through transparently.
