Description
Adjusts the speed of the data source (DTE) UART to the outgoing (modem-
to-modem) data rate. At maximum, this speed is 9600 baud. It is not desirable
to have the serial data fill the modem buffer faster than the outgoing data rate,
since data compression is disabled. The field name has a 6-character blank
default value. The Paradyne products use S90=1 to enable this functionality
while the Intel product uses \J1 to enable similar functionality. This field is
not case-sensitive.
Turns off the default data compression algorithms used by most modems. The
field has a blank field of 6 characters as default. The AT commands that
control this are supported by similar commands; however, these commands do
not operate in the same manner. The Intel modems require H0%C0 to disable
V.42bis & MNP Class 5 data compression algorithms. The Paradyne products
only use %C0 to disable both algorithms. This field is not case-sensitive.
Turns on the V.42 LAPM and MNP error control protocols. The field has a
blank default of 6 characters. The Paradyne products use the command \N5 to
enable V.42/MNP/Buffer error control while the Intel product uses \N3 to
provide similar functionality.
This field has a 20-character blank default and supports any initialization
parameters not already specified. The AT commands specified in this field are
always the last initialization parameters to be sent to the external modem. This
field is not case-sensitive.
This field controls the number of rings required before the modem answers an
incoming call. This field should be set to S0=10.
This field controls the type of interregister signaling used between the modem
and the CO. This 3-character field is denoted by "T" for tone dialing (default)
and "P" for pulse dialing. This setting depends on type of line (tone or pulse)
to the modem.
This field controls the make/break ratios of pulses and DTMF dialing. Most
modems have support for different make/ break options for pulse dialing only.
Paradyne, Intel, and U.S. Robotics use the default &P0 to select a ratio of
39% make and 61% break for communication for the United States and
Canada. The option &P1 sets a ratio of 33% make and 67% break for the
United Kingdom and Hong Kong. This is a 5-character blank field (default)
and is not case-sensitive.
This field has a default of "D" in a 3-character field. This field denotes the
standard dialing command of the modem and is not case-sensitive.
Most modems provide a timer that abandons any outbound data call after a
predetermined interval. This is a non-administrable parameter.
