Freeze the communication after 30 minutes

[Pedro Pinto]

Hello

I have tested on a old PC, direct to RS232 input, and it works without freeze
I will try make tests with another USBtoRS232 converter. The applications must work on a Notebook and today they have not RS232 input anymore.
My USBtoRS232 converter have a Prolific chip and the drives for that are uptodate.

Regards
Pedro

If things dont work, here are 2 options;

a) migrate the project to a USB chip and use a virtual com port on the notebook

b) buy a PCMCIA based serial port card; these are true 16551 UARTs, and are almost as good as having serial ports built-in into the notebook.
