I-MODEM INF README FILE

New Features The MDMUSRIM information file now allows the selection of the 230,400 bps DTE

speed from Windows if you have an external I-Modem and a serial card that

supports the 230,400 bps DTE rate. If you use the 230,400 bps speed selection

from Windows without meeting the previous two conditions, your modem will

not function.

Most PCs do not support the 230,400 bps DTE rate. Consult the documentation

that came with your PC or serial interface card to determine if the 230,400 bps

DTE rate is supported.

Profiles Windows 95/98 users now have the ability to install preset "Profiles” for the

I-Modem using the MDMUSRIM information file. Multiple profiles can be installed

on the same communications port which allows you to change the type of

connection you make with your I-Modem without modifying initialization strings.

For detailed information on installing profiles please see section Installing

Profiles under Windows 95.

Unimodem Driver The release of the I-Modem includes a new Unimodem driver for Windows 95 and

Windows N.T. 4.0. The Unimodem driver for the I-Modem and Total Control

products is MDMUSRIM.INF.

Follow these steps to determine what you will need to do next in order to upgrade

your modem information file to support V.90.
