modem failed to respond

I have a Hitachi Visionbook Elite laptop 166 MHZ with 80 megs RAM running on Win 98.  My pcmcia IBM modem is installed on COM 3.  When I go into COM 3/more info I get "the modem failed to respond".  Port info: Port COM3: Interrupt 5, Address 3E8, UART INS 8250, Identifier PCMCIA\IBM HPC MODEM B89F PCM .  How do I get this to work?
Who is Participating?
IRQ 5 is often used by audio cards. Thus, it's possible you're under a conflict of your modem and audio device.

Go to Control Panel --> System --> Device Manager --> Resources to check if there's any problem.

Besides, COM3 is generally used with IRQ4. Try changing the IRQ to 4 and see if that helps.

The problem was traced to a faulty connection of the pcmcia card to the computer.
Try to Uninstall the modem and re-boot your system. Windows should install your modem on a different interrupt, since it already knew that you have a sound card that is using irq 5. If this don't work try un-installing the sound card and the modem together then re-boot. Make sure you have the drivers for your hardware in case windows will ask for it.

This question was awarded, but never cleared due to the JSP-500 errors of that time.  It was "stuck" against userID -1 versus the intended expert whom you awarded.  This corrects the problem and the expert will now receive these points; points verified.
