PCMCIA - Megahertz DOS Point Enabler 12/08/93
The following instructions describe how to install and configure the
Megahertz PCMCIA modem under OS/2 2.1. These instructions are written
to utilize the DOS based point enabler that ships with this modem.
(Filename: SETMHZ.EXE)
If at all possible, the best way (and the recommended way) to use the
Megahertz modem is to use their OS/2 client device drivers. These
instructions on how to install the DOS based point enablers are provided
by us for those instances where the client device drivers are not
available. To receive a copy of the Megahertz OS/2 client device
drivers for their PCMCIA modem, call Megahertz. Megahertz's toll free
number is (800) 527-8677.
If you are using this modem in a non-IBM machine, then you may not have
the necessary socket services. You should contact the vendor of your
computer to see if socket services are available. If no socket services
are available, you should try to install the point enabler (see following).
------------------------------------------------------------------------------
The Megahertz XJACK PCMCIA Data/FAX modem has been tested under OS/2 and will
work under the limitations listed in the previous section. This procedure is
designed to use the MEGAHERTZ DOS Point Enabler named SETMHZ.EXE. Megahertz
is currently developing an OS/2 Client Device driver for their modem. Below
are the necessary steps required to configure the Megahertz XJACK PCMCIA
Data/FAX modem:
1. Edit the CONFIG.SYS and add the following parameters to the COM.SYS device
driver:
..\COM.SYS (2,2f8,3)
2. You will need to create an input file for the DEBUG utility. You should
create this file in the same directory as the SETMHZ.EXE program. This input
file will be used to zero out the BIOS information at the 40:0 location. See
the following section for an example of the DEBUG.INP file.
3. You will need to create a DOS Batch (*.BAT) file named SETUPMOD.BAT with
the following lines in it:
DEBUG < DEBUG.INP
SETMHZ
Note: This file must be in the same directory as the DEBUG.INP and SETMHZ.EXE
files.
4. After creating the SETUPMOD.BAT file, you should execute it to make sure
that you get no errors.
5. You then should create an ICON to point to the SETUPMOD.BAT file. You
should set the WORKING DIRECTORY to the directory where the SETUPMOD.BAT,
DEBUG.INP and SETMHZ.EXE files reside. This ICON (or DOS Program Object)
should be placed in your Startup Folder so that the modem is initialized each
time you boot OS/2 2.1.
The DEBUG.INP is an input file for the OS/2 - DOS DEBUG utility. This file
contains the keystrokes necessary to place zeros in the ROM BIOS location for
COM2. This is required for the DOS Point Enabler of the Megahertz and other
similar PCMCIA Data/FAX modems. You need to create this file for the steps
listed in the previous section. The DEBUG.INP file must be created EXACTLY as
shown below:
-e 40:2 00
-e 40:3 00
-q
Note: There should be one blank line following the 'q'. The very first line
must be the "e 40:2" line.
