Using Remote Access Service

Modems

This section includes information on using nonsupported modems and

modifying your modem conﬁguration ﬁle, MODEMS.INF, which contains

information describing each modem type supported by RAS. You should not

modify this ﬁle except to add sections for modems that are not already

supported.

Using Nonsupported Modems

If you have a modem that is not supported by RAS, try using the settings for

a modem that is supported. If you are unable to ﬁnd a modem setting that is

compatible, you can modify your MODEMS.INF ﬁle. Consult your modem

manuals or modem manufacturer for further help. This section includes

information to help you modify your MODEMS.INF ﬁle.

Understanding MODEMS.INF

The MODEMS.INF ﬁle lists all the modems supported by RAS, along with

the initialization, dial, and listen command strings each modem needs for

correct operation. When you select a modem during RAS installation, the

Setup program associates the selected modem with the speciﬁed

communication port. RAS connection utilities read MODEMS.INF to obtain

the command strings for the modem associated with each communication

port.

NOTE: The MODEMS.INF file is different for MS-DOS client workstations than for

Windows NT workstations or Windows NT Advanced Servers. Use the

MODEM.INF information in this chapter, rather than the information in the

Windows NT manuals, even if you are connecting to a Windows NT network.

The MODEMS.INF ﬁle consists of two main parts:

•A [default] section

• Individual sections for each supported modem
