Hi Everett and Friends,
Well, my …. IRQ SHARING related real bummer issue is that I have been tryyyyyying 
to replace a dead 3COM 56k PCI controller based modem with the exact same model but 
there are no IRQs available anymore even though I have not added anything new and 
don’t have much hardware on it anyway. I have a 5838 Presario. The installer software 
says “no IRQs available” right away whether I have the new modem in the computer 
or not during the install sequence.

COM2 is “missing” in the Device Manager under the “PORTS {COM & LPT}.
When I fake it… and “install a modem” using the modem install dialog box in the control 
panel … just to see what happens… it installs it on COM1. COM2 and COM3 are not listed 
when I check the DIAGNOSTICS tab… is that relevant? 

However, the COMs listed in my HKEY are COM1, COM2 and COM5. Also, when I put the 
modem it is recognized as new hardware but it thinks it is a “serial port device”, 
not a modem. 

To “check” the new modem out I have tried putting another modem in, and in different 
PCI slots… wheww… but the responses have been the same. Flashed BIOS. Reinstalled 
WIN98. Yeh sure.

When the non-functioning modem first died, I used the diagnostic program on the 3COM 
 CD to look at it. It saw it and said it was AT”ing”and looping OK but it was unable 
to detect dial tones. After I messed around with un-install and whatever else I did??? 
To prepare for the new modem, the 3COM’s diagnostic soft could not see the modem 
at all. The same diagnostic program can’t see the new modem either…  DANG me darn 
it.

ANY clues for me, Stele E  /Boulder, CO
