Windows comms program does not recognise modems on COM3
Return to The Warp Pharmacy:Hardware
Last Updated: 11th February, 1995
Symptoms
When running communications software through a Windows com program, OS/2 would not recognize modems at COM3.
Hardware
ZOOM FaxModem 28.8
Problem
According to IBM, OS/2 reserves IRQ 5 in its system setup for LPT2:. IRQ 5 is also used by COM3.
Procedure
Change com setting on modem to COM1 (best choice).
Notes
Nowhere in the Warp manual does it mention this. I have found that many internal modems come preset for COM3 or COM4. IBM was very helpful once I arrived at the correct phone number (not the 800 number listed in the customer support section)
[ For more information about this situation including alternative solutions, type one or both of the following commands from the OS/2 command line:
