RTS/CTS Enabled
Informs the modem that communication with the data source UART
will be driven with RTS/CTS flow control (6 characters long, default
= \Q3). Field is case insensitive, however, the default is in upper
case. (\Q3)
Asynchronous Data
Mode
Configures the modem as an asynchronous communications device
(8 characters long, default = &M0&Q0). Field is case insensitive,
however, the default is in upper case.
DTE Auto-Data
Speed
Speed of the data source (DTE) UART to the outgoing
(modem-to-modem) data rate (maximum = 9600 baud); field is 6
characters long and case insensitive; default = blank
Disable Data
Compression
Turns off the default data compression algorithms that are in use by
most consumer modems; field is 6 characters long and case
insensitive; default = blank.
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
■ Paradyne products use “%C0” to disable both algorithms.
Enable Error
Control
Turns on the V.42 LAPM and MNP error control protocols, if
available, on the modem; field is 6 characters long and case
insensitive; default = blank.
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.
Misc. Init. Param
Supports any initialization parameters not already specified; field is
20 characters long and case insensitive; default = blank.
The AT commands specified in this free-form field are always the
last initialization parameters to be sent to the external modem.
Auto-Answer Ring
Count
Number of rings before the modem automatically answers an
incoming call; field is 6 characters long and case insensitive;
default is “S0=10” (in upper case). The values 1-255 denote the
number of incoming ring cycles.
Dial Type
Type of inter-register signaling to be used between the modem and
the Central Office; field is 3 characters long, case insensitive, and is
concatenated with the dial string.
T = tone dialing (default in upper case)
P = pulse dialing
