Sending Data over Rs232 for Reprap-controller

Hello,

i designed a small microcontroller board, which can receive data over the rs232 and then controll some FETs to controller a heater for a reprap kind rapid prototyping machine.

Now i need to make EMC2 to send some commands over rs232.

for example if there is an M-Code
M104 S190
it shoud send this command over the serial port

It also has to receive data from the rs232, for example if a M105 is exectuted, the M105 should be send to the microcontoller board, which sends back the current temperature (to display it in a bar or something)

How can i implemnt these thing?

Thanks in advance

look here for ideas:

thanks.. ill check tose links...

thanks a lot, that should work, i think i'll do it this way
