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

If your modem is already listed in your Control Panel, Modems list, you will need to update your information file to support your V.90 modem.  Skip to the section of this document titled "Updating your Courier I-Modem information file to support V.90".  If your modem is not listed in Control Panel Modems skip to the section of this document "Installing your Courier I-Modem information file to support V.90".

NEW FEATURES

The MDMUSRIM information file now allows the selection of the 230,400 bps DTE speed from Windows on external Courier I-Modem models.  You can only use the 230,400 bps speed 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 Courier modem will not function.  Please note, 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 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 will allow 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 the section of this document titled "Installing Profiles under Windows 95".

INSTALLING PROFILES UNDER WINDOWS 95

The profile feature of the MDMUSRIM information file allows you to install multiple instances of your Courier 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 choose what type of connection 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 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:

1)  Go to Control Panel, Modems and click Add.

2)  Check the box that says "Don't detect my modem; I will select it from a list" and click Next.

3)  Select U.S. Robotics Access Corp from the manufacturers list.

4)  From the Models list choose the profile you want to install. If you have an internal model install the "I-Modem INT" profiles.  If you have an external model install the "I-Modem EXT" profiles.  Click Next.

5)  Choose the communications port where your I-Modem is installed and click next.  Windows will install your profile.

6)  Click Finish.

7)  Repeat the procedure for each profile you want to install.

Using your profiles.

1)  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 connections refer to the I-Modem Getting Started Guide 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 that is used to restore your modem to these settings is AT&F1*V2=5*D0=0.

Be aware that Windows still views each of these profiles as independent devices so you can't use two profiles with two different programs simultaneously.  For example if you have 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.
