How to read AT Command response using Synaser

[lqman]

Hi All.

I try to create application similar function with hyperterminal using synaser library.
Main purpose is user can send (AT Command) to serial port and get the answer.

My program already run with this concept :
1. Open Serial port with synaser.
2. Send AT command using synaser function :

Code: [Select]

TBlockSerial.ATCommand("AT command text");3. Wait for the respond with timer, try to read the recvString.

Code: [Select]

serialPort.Recvstring(0)
The program run successfully, but I want to change the 3rd point, not use timer, but use like event handler (in C) or raise event (in vb).

Any help will be appreciated....
Thx.

instead using timer, better to use thread. increase reading timeout on synaser to about 500ms - 1000ms. do reading and data processing inside thread loop and use callback to communicate with your main thread (your gui for ex.). don't forget use synchronize when call your callback.
