I'm trying to help out a co-worker with a computer problem she is having. I don't have much knowledge on IRQs, but I believe that is her problem. She has a computer without the PS/2 ports, so her mouse hooks up to the first serial port at Com 1. Her modem is a Zoom 56k external modem. I hooked it up to her other serial port, but nothing seems to work. The modem installs but never makes any communication. It says it is installed on Com 2, but when I go into the diagnostics tab and click More Info on Com 2, I receive an error stating that it couldn't open the port. If I click out of the error, a box pops up displaying the port info. It says Com 2, Interrupt: 0, Address: 0. When I check the IRQ list in Device manager, there is no Com 2 assigned to any IRQ. I thought Com 2 was supposed to be at IRQ 03. Nothing at all is assigned to IRQs 03 and 09. They don't even appear in the list. Com 1 does show up at IRQ 04. What can I do to fix this? She doesn't have much on her computer becasue she's never had internet access. Should I backup her documents, format, and re-install Win98? Could that possibly help? She received this computer from some organization. It was never redone for her. Stuff was just deleted and then the computer was given to her. Any help is greatly appreciated.
