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.
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.
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.
