NEW FEATURES

The MDMUSRIM information file now allows you to select a 230,400 bps 
DTE speed from Windows if you have an external I-Modem AND a serial 
card that supports a 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 a 
230,400 bps DTE rate. Consult the documentation that came with your 
PC or interface card to determine if the 230,400 bps DTE rate is
supported.

Windows 95 users now have the ability to install preset "Profiles" 
of 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 95/98.

The V.90 release of the I-Modem includes a new Unimodem driver for 
Windows 95, Windows 98 and Windows NT 4.0. The Unimodem driver for 
the I-Modem and Total Control products is MDMUSRIM.INF.

Follow these simple steps to determine what you will need to do next 
in order to upgrade your modem information file to support V.90.

INSTALLING PROFILES UNDER WINDOWS 95/98

The profile feature of the MDMUSRIM information file allows you to 
install multiple instances of your I-Modem on the same communication 
port. This will allow you to change the type of connection you make 
with your I-Modem without modifying initialization strings.  You can 
choose the connection type you would like to make by choosing a 
different modem profile in the "connect using" dialog box of Windows 
95 Dial Up Networking.

In addition to the standard I-Modem driver the MDMUSRIM information 
file allows Windows 95/98 users to install the following modem 
profiles:
	
	I-Modem EXT (V.120 Profile)
	I-Modem EXT (TurboPPP 128K Profile)
	I-Modem EXT (TurboPPP DBA Profile)
	I-Modem EXT (Forced Analog Profile)
	I-Modem INT (V.120 Profile)
	I-Modem INT (TurboPPP 128K Profile)
	I-Modem INT (TurboPPP DBA Profile)
	I-Modem INT (Forced Analog Profile)

V.120 Profile  - 	for autodetect 56/64K V.120 or analog type 
		 	connections (Initializes modem with *V2=0)

TurboPPP 128K Profile - for MultiLink PPP connections when you want 
			both B channels to always be connected 
			(Initializes modem with *V2=5*D0=1)

TurboPPP DBA Profile - 	for Multilink PPP connections when you want 
			the second B channel active only when it is 
			needed (Initializes modem with *V2=5*D0=0)

Forced Analog Profile - for instances when you want to force an 
			analog type connection.  (Initializes 
			modem with *V2=3)

To install a profile under Windows 95/98:

	1) Go to Start --> Control Panel
	2) Double-click Modems.
	3) Click Add.
	4) Check the box that says "Don't detect my modem; I will 
	   select it from a list" and click Next.
	5) Select U.S. Robotics Access Corp from the manufacturers 
	   list.
	6) From the Models list choose the profile you want to 
	   install.  If you have an internal model use the 
	   "I-Modem INT" profiles.  If you have an external model 
	   use the "I-Modem EXT" profiles.  Click Next.
	7) Choose the communications port where your I-Modem is 
	   installed and click next.  Windows will install your 
	   profile.
	8) Click Finish.
	9) Repeat the procedure for each profile you want to 
	   install.

Using your profiles.

	1) On your desktop, double click My Computer.
	2) Double click the Dial Up Networking folder.
	3) Right click one of your connections and choose 
	   properties.  If you do not have any connections 
	   refer to the I-Modem Getting Started Guide and the 
	   Command Reference (found on the CD-ROM) for help on 
	   setting up connections.
	4) Under the General Tab you will see a box to select the 
	   modem you want to use for your connection. Click the 
	   drop down box and select one of your I-Modem profiles.
	5) Click OK.

	When you double click this connection the modem will be 
	initialized according to the profile you selected.

	When you have completed your connection click the Disconnect 
	button. Your I-Modem will return to it's factory default 
	settings of the Hardware Flow Control template and Multilink 
	PPP with Dynamic Bandwidth Allocation.  The initialization 
	string used to restore your modem to these settings is
	AT&F1*V2=5*D0=0.

	Windows views each of these profiles as independent devices. 
	You cannot use two profiles with two different programs 
	simultaneously.  For example if you use a fax application in 
	auto answer mode with the forced analog profile you will not 
	be able to dial out with Dial Up Networking using the V.120 
	profile because the fax application already has control of 
	the communications port.
