CATEGORY:  Driver

EFFECTIVE DATE:  09-14-94

PRODUCTS AFFECTED:  Contura Aero, LTE Elite, Contura 400

OPERATING SYSTEM:  MS-DOS 5.0 or greater

SYSTEM CONFIGURATION:  PCMCIA slot(s) and PCMCIA modem as COM1

DESCRIPTION:  MDMCOM1.SYS (dated 9-14-94) allows Windows-based apps to
communicate with a PCMCIA modem that is assigned to COM1. 
  Normally PCMCIA modems are set for COM2 (for some sound technical reasons)
but some customers insist that the modem be set for COM1.  Setting the 
PCMCIA modem to COM1 may cause Windows apps to be completely unable to 
talk to the modem - MDMCOM1.SYS allows normal operation for those apps.
							       


HOW TO USE: 

1. If SoftPaq obtained on diskette, copy the SoftPaq file to a temporary
   directory on the hard drive and go to that directory:

     MD C:\CPQ
     COPY A:\SP0936.EXE C:\CPQ
     C:
     CD \CPQ

2. From that drive and directory, run the SoftPaq utility to unbind the
   primary files.  Type SP0936.EXE (and press ENTER). The following files 
   should be created: 

     MDMCOM1.SYS  MDMCOM1.DOC

3. Please read all DOC files before installing this new driver.

4. Copy the MDMCOM1.SYS to the \CPQDOS subdirectory:

     COPY MDMCOM1.SYS C:\CPQDOS

5.  Edit your CONFIG.SYS file and add a line for MDMCOM1.SYS:

     CD\
     EDIT CONFIG.SYS

       Cursor down and insert a line that
       says "DEVICE = C:\CPQDOS\MDMCOM1.SYS"
       just above the one that says "REM *** Begin PCMCIA Drivers ***".
       Save the file and exit.

6.  Change the PCMCIA configuration to place the modem on COM1.

     CD \CPQDOS
     PC-CARD

     Hit Return to clear the initial screen.
     Then hit ALT-F and E to edit configuration.
     Hit ALT-M to change modem configuration.
     Change the field "Slot1: COM2"  to  "Slot1: COM1" and
      hit TAB to move to "Slot2: COM2" and change it to "Slot2: COM1".
     Hit Return twice to get back to main menu.
     Hit ALT-F and S to save the configuration.
     Hit ALT-F and X to exit to DOS.
     Hit CTRL-ALT-DEL to reboot.

7.  While rebooting hit F10 to start SETUP so that the system board serial
   port can be set for COM2.

    Once in SETUP, click on "Communications"
    In the box labeled "Serial Interface 1",
       click on the choice that says "Address 2F8h, IRQ3"
    Click on OK to close the Communications box.
    Click on Exit to exit Setup.
    Exit Diagnostics and let the system reboot, it is now ready to use.
