Im trying to communicate to a serial device via the COM port. Im using hyperterminal and when i try and send my data I dont see anything in Hyperterminal. I have double checked and triple checked the budrate and any other protocol. I ahve gone into device manager and looked at the COM port it says its installed correctly no error. What can I do to further test this?

The device on the other end of the link may not be echoing characters.  There is usually an option in terminal emulators called "local echo."  If this is enabled, typing is displayed on the screen without the necessity of the  remote device echoing it.

OK

Now in the device manager, hit scan for hardware changes

It should find the port and the device should be recognized

OK

Right click on that one and re-enable it, then uninstall it

Reboot the machine with the device plugged in

It should reinstall the port

Then try connecting again

I doubt it.  You will be stuck on the phone for hours until they transfer you to india and then you wont be able to understand anyone....

Under curiosity, exactly what are you trying to do anyway?  What kind of device?

its a data collector we manufacture to send reading to a serial com. In this case this data collector uses a null modem to communicate to a PC.

oh, sorry...

i would try a different device and see if it works properly

if not, maybe run a repair installation in windows and restore corrupted system tools, drivers, and devices

I ran a windows repair and ten updated drivers from the DELL website.
