Common Problems
Listed below are possible solutions to problems you may encounter:
Card Services does not recognize your DIVA T/A.
If PC Card Services does not recognize your DIVA T/A, check for a
memory conflict. Card Services software requires a 4K-memory
window to read the Card Information Structure (CIS) of the PC Card.
Exclude this window from your memory manager (EMM386.EXE).
To determine which window Card Services uses, refer to your Card
Services documentation.
Another possibility is that CARDID.EXE is not loaded using
CARDSOFT for DOS.
Card Services does not configure your DIVA T/A.
If PC Card Services does not automatically configure your DIVA
T/A, your Card Services Generic Enable may be improperly
configured. Most Card Services provide Generic Enable that
automatically assigns the next available COM Port to the device. The
name of the Generic Enable may differ depending on your Card
Services provider. For more information, refer to your Card Services
documentation.
“Port in Use” Error.
The DIVA T/A uses a port that is already in use. Normally, PC Card
Services assigns a COM port to each newly inserted device and
maintains a list of COM ports in use. To solve this problem, have PC
Card Services assign an available port to the DIVA T/A.
“The COM Port is either in use or unavailable” or
“Port not open” Errors.
The wrong Interrupt Request Line (IRQ) may be assigned to the COM
port. Most computers have pre-assigned IRQ numbers for each COM
port. If a conflict occurs, the DIVA T/A can use any IRQ. To solve
this problem, have PC Card Services reassign your COM port and
IRQ.
