different manufacturers and attempt to prevent all conflicts between different PCMCIA cards.

The main disadvantage of using Card and Socket Services are that they permanently occupy a certain amount of laptop or desktop memory, which could be used by other programs.

Most Card and Socket Service programs are loaded from the CONFIG.SYS file and use from 40K to 85K of memory space. If Card and Socket Services is running properly on your machine, then your Serial Card will be recognized and configured properly by simply inserting the card into one of the PCMCIA slots.

Point Enabler Users

Point Enablers are programs that run, enable a specific device (such as your B&B Electronics Serial Card), and exit. Point Enabler commands are typically installed in the AUTOEXEC.BAT file so that they will be executed once each time the laptop or desktop is turned on. The advantage of a Point Enabler, is that it uses system memory only while it runs. The disadvantage is that when the PCMCIA device is powered off, the user must remember to execute the Point Enabler command to re-enable the Serial Card. Another disadvantage in using Point Enablers is that you need a different one for each manufacturer's PCMCIA device. One manufacturer's Point Enabler may conflict with another's Point Enabler. A Point Enabler program may also conflict with an already running Card and Socket Service program. It is best NOT to run a Point Enabler if Card and Socket Services have already been loaded on your PC.

Using the Point Enabler Program

B&B Electronics has supplied a Point Enabler program called ENABLE.EXE. To use this program perform the following:

1.Copy the file “ENABLE.EXE” from the supplied diskette onto your root directory. (Typing ENABLE /? on the command line will bring up a program help screen.)

2.Use a text editor to add the following line to your AUTOEXEC.BAT file:

ENABLE /com2 /sA /MD000
