You can not set the pause correctly. TIES modems do no support
the pause (which is how they got around the Harward patent in the first
place) while non-TIES modems (Hayes / Hayward compliant) already have the
delay set. The fix is to disable the escape sequence character to either
127 or 255 (depending on modem) with the command ATS2=255&W or ATS2=127&W
which can be done in a TIES bomb payload.
