To ansmer yours questions, i would like to make a C or C++ program which communicate via the serial port COM1 to a device. The device is a screen plasma. I would like the program to remote the sreen : switch on, switch off, change channel ...
The serial communication setting is :
Baud : 4800 BPS
Data length : 8 bits
Parity : none
Stop bit : 1 bit
Flow control RTS/CTS
Communication code : ASCII code
Reception time out : 4 seconds
To do it, I need to send ASCII code. For exemple, to switch off the screen i must send the "%A0001" code.
I need to receive the acknoledgment to know if it has been well done. (code for good receive : "@S")
Thanks for your help.
