Using Remote Access Service
Modems
When you select a modem during RAS installation, the Setup program looks
for a section with the name [modemname.INIT]. If it does not find one, it
uses the initialization strings defined in the [default] section.
For example, the Hayes Smartmodem 2400™ uses the same set of command
strings as listed in the [default] section. Therefore, the only line in the
[Hayes_Smartmodem_2400] section is the MAXBAUD line.
#-----------------------------------------------------------------
[Hayes_Smartmodem_2400] MAXBAUD = 2400
The Intel_9600EX modem, however, uses different initialization strings
from those shown in the default section. Therefore, these strings are defined
separately in the [Intel_9600EX] section.
#-----------------------------------------------------------------
[Intel_9600EX]
# \N1 Direct Mode
# Command line length cannot exceed 40
MAXBAUD = 9600
[Intel_9600EX.INIT]
[Intel_9600EX.COMMAND]
command = AT&F&C1&D2 V1 S0=0 S2=128 S7=55 &Q0 \N1*cr
[Intel_9600EX.INIT.RESPONSE]
OK = *cr*lfOK*cr*lf
ERROR = *cr*lfERROR*cr*lf
#-----------------------------------------------------------------
Because the Intel_9600EX modem uses the LISTEN and DIAL strings listed
in the [default] section, only the INIT strings need to be listed in the
[Intel_9600EX] section.
If a modem's command strings are identical to those already listed for
another modem, the name of the latter modem can be used as an alias for the
former. For example, the MODEMS.INF section for Hayes_Ultra reads:
#-------------------------------------------------------------
[Hayes_Ultra]
MAXBAUD = 9600
Alias=Hayes_V_Series_9600
The Alias line tells the Setup program that the Hayes Ultra modem uses the
same command set as the Hayes V Series 9600 modem.
