new modem install - unable to open com port

  sims 13:56 01 Apr 2004

I had a pci modem that would forcibly install to com5 which the Juno internet-connection software would not recognize; although it did work at some point in the past. I have replaced it with a new pci modem, removed all existence of the old (including registry), and installed new driver software. The new modem installs to com2 or com3 but I continue to receive the error: "Cannot open com port" no matter what I try. I am ready to chuck the whole pc - please help.

What operating system, motherboard and modem?

An answer will depend on these...

you want to follow the info that came with your modem and check to make sure the IRQ's and intterupts are set properly.

Try changing the com port and see if this fixes it. Mine installed itself on the wrong one and changing the com port got it going.

I have had real problems with PCI modems and so called virtual ports.

Try first to delete the moden in device drivers and reboot this might allow it find a port that works.

Also sometimes you may find that removing the PCI card, rebooting and then refitting may sort it out.

Conflicts of ports can be a pain.

try this. go into control panel then select ports.
select com port 2 and then change the resources to the following.
I/O Range 03E8 - 03EF and the IRQ to 03.
restart computer and go back into diagnostic.
let me know how you get on.

I have found on a couple of occasions, when installing a new modem, that deleting the modem AND the Dial Up Networking and then making a new connection and point the DUN to the new modem driver helps when installing a new modem.
