Result codes. These are the messages generated by the modem when
connection or disconnection is attempted.
There are 5 sets of result codes available (numbered 0 - 4). The ATX
command is used to select which result code set to use. The selection of the
result code set, also affects the way the modem detects dial tone and busy
tones.
ATX0 Selects the Basic code set. In this mode dialling will be carried out
regardless of whether a dial tone is detected or not (this is called Blind
Dialling). If successfully connected, the 'CONNECT' message will be returned
from the modem. No indication is made as to the speed the modem is
connected at.
ATX1 - Selects the extended result code set. Connection is as for X0 except
that the modem now indicates the connection speed in the connect message,
e.g.
"CONNECT 300" when connected at 300bps, "CONNECT 1200" when
connected at 1200bps.
ATX2 - Same as ATX1 with the addition of dial tone detection.
ATX3 - Same as ATX1 with the addition of busy tone detection.
ATX4 - Same as ATX1 with addition of dial tone and busy tone detection.
These commands are for compatibility only.
