Hello everyone,

although I'm using CAN, I can't get away of being interested in communicating via the "normal" serial port of the 8052 microcontrollers.

Lets assume, I want to connect 10 microcontroller slaves by a full duplex RS232 connection to one master PC. (Each slave can always listen to the master PC, while only one of them should answer at the same time).

Now I send a message of, lets say, 30 databytes to one of the slaves, wich answers by a 30 bytes datablock.

The messages could be corrupted by noise, etc.

What I would be interested in is an easy to use implementation (!) of a reliable data transmission protocol to do this job.

Wich one can you recommend?

Thank you!

Mike
