Macintosh Portable Data Modem 2400: Dialing Without Dial Tone



We have had reports that the Macintosh Portable Data Modem 2400 cannot
find a dial tone when plugged into an internal switchboard. The Hayes
commands to do this, although accepted by the modem, seem to have no
effect.

Setting the active result codes with the X command tells the modem to:
- dial after a delay set by modem register S6, and
- not wait for a dial tone.

Use the following commands. You may or may not need to set register S6,
depending on the phone system in use. The text in parentheses is comment
only, and not part of the commands.

ATX3 (OK, CONNECT, RING, NO CARRIER, ERROR, CONNECT 1200 & 2400, BUSY)
ATS6=3 (Wait 3 seconds. Default is 2, so this probably isn't necessary.)
