i use my serial port Com1 for use with my PDA and recently i get this error when i try to link up. it is as if some program or app is running in background from stratup and i can't figure out what it is. i don't know enough about the proccesses running in task manager to figure out what should and shouldn't be running. is there a S/W i can download that would look at my com ports and tell me what program is using it?
help please, my pda is not the only piece of equipment i need the serial port for.

Try disabling all aps in the Windows Startup Menu except for your anti-virus program, firewall, anti-malware aps that give realtime protection (Like Spybot if you have Teatimer enabled) and essential Windows aps.

I recommend Startup Inspector for managing the startup menu because it does a much better job of identifying the aps than the Windows Utility, msconfig does.

Startup Inspector freeware (manages startup menu helps you identify aps in the startup menu so you can disable unnecessary programs from running in the background when they are not needed)

Startup Monitor (a small freeware ap available on the same page to notify you and require your permission for any program to add itself to your startup menu)


What other devices do you use the serial port for? You might be able to use USB instead.

In any case, do as I suggested above and it may eliminate your problem.
