Asynchronous Data
Mode
This field will configure the modem as an asynchronous commu-
nications device. This field is 8 characters long with a default of
“&M0&Q0”.
This field is case in-sensitive; however, the default will be in
upper case. (&M0&Q0)
DTE Auto-Data Speed
This option will adjust the speed of the data source (DTE) UART
to the outgoing (modem-to-modem) data rate. So, at maximum
this speed would be 9600 baud.
This field is 6 characters long with a blank as default.
This field is case in-sensitive. ( )
Disable Data
Compression
This field will turn off the default data compression algorithms
that are in use by most consumer modems. This field is 6 char-
acters long with blank as the default. The AT commands that
control this capability are supported by similar commands; how-
ever, these commands do not operate in the same manner.
The Intel modems require the use of “H%C0” to disable V.42bis
& MNP Class 5 data compression algorithms; however, the
Paradyne products only use “%C0” to disable both algorithms.
This field is case in-sensitive; with blank as the default. ( )
Enable Error Control
This field will turn on the V.42 LAPM and MNP error control pro-
tocols, if available on the modem. This field is 6 characters long
with “blank” as the default.
This V.42/MNP/Buffer mode first attempts to negotiate V.42 error
control with the remote modem. If this fails, then the modem
transitions to MNP, and if this fails then no error control is used.
This field is case in-sensitive. ( )
Misc. Init. Param
This field is 20 characters long with blank as the default. This
field supports any initialization parameters that are not already
specified. The AT commands specified in this free-form field will
be always the last initialization parameters to be sent to the
external modem.
This field is case in-sensitive; however, the default will be in
upper case. ( )
