$EnV.42 Error Correction at 300 bps
n
= 0 or 1
Default: $E0
At 300 bps, error correction is not normally used.
$E0 disables 300 bps/V.42 error correction altogether.
$E1 enables the modem to function at 300 bps in non-error correction (&E0), auto-reliable (&E1), or
reliable (&E2) mode.
$AnAuto-Reliable Buffering
n
= 0 or 1
Default: $A0
In auto-reliable mode, the modem has four seconds to establish a reliable connection, after which the
modem drops to non-error correction mode. Any data received during this period will normally be
discarded. The $A command causes the modem to buffer (store) data that is received during the auto-
reliable time-out period. This data is then output by the modem after the CONNECT
message.
$A0 discards the data received during the auto-reliable time-out period.
$A1 buffers data received during the auto-reliable time-out period.
$FnAuto-Reliable Fallback Character Enable/Disable
n
= 0 or 1
Default: $F0
In auto-reliable mode, the modem has four seconds to establish a reliable connection. If a single carriage
return is received from the remote modem during this period, the auto-reliable modem assumes that the
remote modem is not in reliable mode, and drops to non-error correction mode. The carriage return is the
only character that causes the modem to drop to non-error correction mode. Any other data is either
buffered or discarded.
Use the $F command to enable this feature.
You can use the auto-reliable fallback character ($F) and auto-reliable buffering ($A) commands together
to cause the modem to buffer all data received up until the carriage return, and then drop to non-error
correction mode. All data received is then output following the CONNECT
message.
$F0 causes the modem not to fall back to non-error correction connect if a carriage return is received.
$F1 causes the modem to fall back to non-error correction connect if a carriage return is received.
