Can you help me to communicate between a 8051 based micro controller and a PC via RS232 ?
I built this µC system some years ago; the PC interface is written in Qbasic.
Everything was all right untill I switched to Win XP.
I'm looking for either a Qbasic version supported by XP or an RS232 diver useable for instance in visual basic.
Thanks a lot in advance

Often recompiling the source code on the new machine fixes the problem.
