4.1.4 Common Problems

Generic Client Drivers:

Many Card and Socket Services packages include a generic client driver (or "Super Client") which configures standard I/O devices. If one of these generic client drivers is installed, it may configure the QSP-200/300 causing the QSP-200/300 client driver to fail installation. In these cases, the user should do one of the following:

1.modify the operation of the generic client driver to disable the configuration of modem/serial port cards. Consult the Card and Socket Services documentation for availability and details of this feature.

2.place the QSP-200/300 client driver before the generic client driver in the

CONFIG.SYS.

Available Resources:

One function of the Card and Socket Services software is to track which system resources (memory addresses, I/O addresses, IRQs, etc.) are available for assignment to inserted PCMCIA cards. Sometimes, however, the Card Services software assumes or incorrectly determines that a particular resource is used when it is actually available. Most Card and Socket Services generate a resource table in a file (typically in the form of an .INI file) which the user can modify to adjust the available system resources. Consult the Card and Socket Services documentation for availability and details of this feature.

Multiple Configuration Attempts:

Some Card and Socket Services have a setting which aborts the configuration process after a single configuration failure (such as a request for an unavailable resource). The user should change this setting to allow for multiple configuration attempts. Consult the Card and Socket Services documentation for availability and details of this feature.

Older Versions of Card and Socket Services:

Some versions of Card and Socket Services dated before 1993 do not support general purpose I/O cards. If after careful installation of the Client Driver the QSP-200/300 does not configure or operate properly, an updated version of Card and Socket Services may be required. Card and Socket Services software is available from Quatech Inc.

4.2 QSP-200/300 Enabler for DOS

For systems that are not operating PCMCIA Card and Socket Services software, the QSP-200/300 DOS Enabler may be used to enable and configure the adapter. This Enabler, QSP200EN.EXE, will operate on any DOS system using an Intel 82365SL or PCIC compatible PCMCIA host adapter including the Cirrus Logic CL-PD6710 / 6720, the VLSI VL82C146, and the Vadem VG-365 among others.
