6 Modems and FOSSIL drivers
FrontDoor works with several modems, including US Robotics HST and
HST/DS, Telebit's Trailblazer, ANC, Everex and Hayes. The general
rule is that the modem must be able to send alphanumeric result
strings. For most modems, the basic configuration is all that is
required. For high speed modems such as the HST, a few extra settings
are necessary.
To utilize your modem in the most efficient way, it must be properly
configured for use with FrontDoor. Most modems are incorrectly
configured for use with FrontDoor when they leave their factory.
FrontDoor require that your modem can return verbal result codes,
such as "CONNECT 2400" and "NO CARRIER". In addition, if you want
FrontDoor to answer the telephone on inbound calls, the modem must be
able to return a verbal code indicating a ring signal, such as
"RING". The modem must not have CD (carrier detect) forced. It should
support disconnecting by lowering DTR (data terminal ready), but it
is not necessary. DTR must not be forced.
For high speed modem users, it is usually recommended that you lock
the DTE (computer<>modem) speed to the highest possible baud rate;
which is usually 19.2 or 38.4 KBPS.
The current version of FrontDoor does not support manually operated
modems with fixed speeds since most of them do not send any type of
messages to the terminal (program). This is expected to be
implemented in future versions.
