Before You Begin
Please read the following tips carefully before attempting to
install your new modem.
For DOS/WINDOWS 3.1X INSTALLATION
Most portable computers sold today include some form of Card and Socket
Services. This software enables the computers internal PCMCIA controller
to operate. If the computer beeps when the modem is inserted, the modem
should be configured and ready to use. If you do not have Card and Socket
Services, follow the procedure for installing the Point Enabler in this section.
Windows 3.1 and Windows for Workgroups 3.11 do not require any special
drivers to communicate with the PC Card fax/modem if you are using your
systems Card and Socket Services software. You only need to install com-
munications software. If the version of the modem you purchased included
communications software, go to the section Installing and Configuring Soft-
ware and follow the installation instructions.
If your computer does not have Card and Socket Services you will need to
install the Point Enabler. This program provides DOS with the necessary
drivers to interface with the modem. However, you will not be able to hot
swap the modem. The Point Enabler will have to be reinstalled any time you
insert or remove the modem. To install the Point Enabler in your system,
insert the installation diskette that came with your modem into the computers
floppy disk drive. Find the file pmxfm.exe and copy it to the root directory
of your default hard drive. The Point Enabler needs to be executed each time
you turn on your computer. This can be done by typing the following com-
mand line at the DOS C:> prompt:
pmxfm c=n i=nn <enter>
Where c specifies the COM Port number (from 1 to 4) and i specifies the
Interrupt used (from 1 to 15). Using COM 3 and IRQ 9 will work in most
systems. Once the pmxfm.exe driver has been loaded and is working cor-
rectly, you can add the statement to your autoexec.bat file.
Example: pmxfm c=3 i=9 <enter>
You may also need to modify your config.sys file to exclude an address range
when using the Point Enabler. The two examples below show the most effec-
tive ranges and will work with the majority of computers. Example A: shows
the most common exclusion range. Example B: may be the preferred setting
