SPEEDSTER 288 INTERNAL FAX/MODEM
Register
Default
Function
S9
6
Sets the required duration, in tenths of a
second, of the remote modem’s carrier
signal before recognition by your modem.
S10
7
Sets the duration, in tenths of a second, that
the modem waits after loss of carrier before
hanging up. This guard time allows the
modem to distinguish between a line hit, or
other disturbances that momentarily break the
connection, from a true disconnect (hang up)
by the remote modem.
While we don’t recommend connecting the
modem to a line with call waiting, if you have
it, you may wish to adjust this setting upward
to prevent the modem from misinterpreting the
second call signal as a disconnect by the
remote modem. A better alternative is to
ask your phone company how to temporarily
disable call waiting (usually *70W). For
example:
ATDT *70W
phone number
.
Note: If you set S10 = 255, the modem will not
hang up when carrier is lost. Dropping DTR
hangs up the modem.
S11
70
Sets the duration and spacing, in milliseconds,
for tone dialing.
S12
50
Sets the duration, in fiftieths of a second, of
the guard time for the escape-code sequence.
