RTS/CTS Enabled
This field will inform the modem that communication with the data
source UART will be driven with RTS/CTS flow control. This field is 6
characters long with a default of “\Q3”. This field is case in-sensi-
tive; however, the default will be in upper case. (\Q3)
Asynchronous
Data Mode
This field will configure the modem as an asynchronous communi-
cations 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 characters
long with blank as the default. The AT commands that control this
capability are supported by similar commands; however, 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 proto-
cols, 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 transi-
tions 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. ( )
