Configuring the Serial Card

Once the Serial Card has been inserted, the PCMCIA socket must be configured for serial port operation. All PCMCIA input/output devices must be configured by software before they can be used. This configuring/enabling process must be repeated (that is, the enabling program must be run again) whenever the Card is powered off, then on again. A PCMCIA Serial Card will be powered off when the user removes it from the laptop and then re-inserts it. It may also be powered off, when the laptop goes into a "sleep" mode to conserve power.

There are two kinds of PCMCIA enabling software: Card and Socket Services, and Point Enablers. You must choose which software enabling method you will use to activate your Serial Card. Each method has its advantages and disadvantages. (See Card and Socket Service Users section or Point Enabler Users section for more information.)

Most laptops and desktops, that come equipped with PCMCIA slots, come with Card and Socket Services (CSS) software. This software manages the PCMCIA ports. If Card and Socket Services are running on your machine, your Serial Card will be set up and configured for you automatically when you insert the card into the PCMCIA slot. This is usually the easiest and best way to configure your Card. In most cases all you will need to do is plug in your Serial Card and access the assigned COM port. (Refer to your PC documentation for information concerning the Card and Socket Services provided with your system.)

Software Setup

Once your card is configured, it can be accessed through your application software by choosing the appropriate COM port. (Refer to the users manual associated with the software you are using for information on how to assign COM ports.)

Card and Socket Service Users

Card and Socket Services is a set of programs that are installed so that they are executed when the laptop is turned on. The Card and Socket Service programs then stay resident - they remain in memory all of the time. Card and Socket Services are designed to detect when a PCMCIA device has been inserted or powered off and then it automatically re-enables the device. This allows "hot swapping" - you can pull a PCMCIA card out and put in a different one and the new card is automatically enabled. Card and Socket Services also "know" how to enable a variety of devices from
