Serial com how to assure it is working properly?

[zillah]

I have got new laptop Dell Latitude D620 with win2003 OS SP1 all updates installed.

I have been experiencing a problem: when I used two emulators : HyperTerminal or SecureCRT, I can not connect to Cisco devices ( not only one device,,,,that means there is no possibility that a device is defected) .

There is no problem with a cable that connects my PC to a Cisco device, because the same cable with another PC is working fine.

There is no problem with windows OS 2003, because when I installed the fresh copy of 2003, the same problem is still going on!!!!!!

I have been advised that might be the problem with serial com port.

How can I verify (assure) that com port is working properly, and the problem with something else ?

I have checked BOIS, com enabled

And you can the Figure of device manager in the link below as well:

Any other suggestions ? Do I need to do some test ?

Thanks

update all your chipset drivers and any other PCI devices you may have.

drivers for XP:

I was aware of that, but I could not get it work

so you tried the drivers and still didnt work? or you couldnt get the drivers to work? if its the latter go into device manager:

start>run and type devmgmt.msc

then you can right click devices choose update drivers and go to the folders manually so the drivers update. If its not the right driver it normally it wont try updating.

What basically I did , I attached serial dial up modem to the laptop's com, and I installed the modem , it was installed successfully without any problem , and I run the modem diagnostic test, it was ok.
