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 and is case in-sensitive. (&K0)
Enable Error
Control
This field will turn on the V.42 LAPM and MNP error control
protocols, if available on the modem. This field is 6 characters long
and is case in-sensitive.
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
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 20 characters long and is case in-sensitive. ( )
Auto-Answer
Ring Count
This field controls the number of rings required before the modem
automatically answers an incoming call, if and only if the switch
doesn’t answer first. (If the switch is healthy, it answers an
incoming within the first few rings.) This field is 6 characters long
and is case insensitive. Typically, the maximum permissible value
for this register is 255. The values 1-255 denote the number of
incoming ring cycles. (S0=10)
NOTE:
The number of rings is optimally set above 5, and if at all
possible, keep the default of S0=10.
Dial Type
This field controls the type of inter-register signaling to be used
between the modem and the Central Office. Use “T” for tone dialing
and “P” for pulse dialing. The field length is be 3 characters long
and is case in-sensitive. This field will be concatenated with the dial
string. (T)
Adjustable
Make/Break
Ratio
This field can be of particular importance when using a modem that
may be transferable from country to country. The intent of this field
is to control the make/break ratios of pulses and DTMF dialing. The
Intel product information has support for the different make/break
options for pulse dialing only.
Intel uses the option “&P0” to select a ratio of 39% make and 61%
break for communication within the U.S. and Canada. The option
“&P1” sets a ration of 33% make and 67% break for the U.K. and
Hong Kong.
This field is 5 characters long and is case in-sensitive. ( )
Dial Command This field simply denotes the dialing command of the modem. This
is a fairly standard command. (D)
