Notebook Com Port win2k problems

[Luciano]

Hi,

Is the board powered off the COM port?
In some notebook computers the COM port provides very marginal voltages.

Best regards,

Luciano,
The handyboard serial interface board a seperate power supply input from the microcontroller. The only connections to the PC are TX, Rx, and ground.
I forgot to mention that the interface board green ser. led does illuminate briefly when windows is booting, but extinguishes when the 'windows splash' displays. Since my first post, I've also checked this on a Win98se notebook with the same result.

Not sure what changed, but the Win 2k notebook PC is now communicating just fine with the Handyboard Serial Interface & Battery Charger board. Thanks.
