Interrupt not working?

[Demon]

Is that too much stuff going on inside ISR?

What if you simplify usart logic until you get things working as expected?

Do you really need byte-by-byte reception? Can you get away with a fixed length message?

My interrupt routine looks like this:

ReceiveInterrupt:
  HSERIN 50,No232,[DEC5 PicIn.byte1, DEC5 PicIn.byte0, DEC1 CommandIn, _
                   STR DataIn1\24, STR DataIn2\24,                     _
                   DEC5 CheckSumIn.byte1, DEC5 CheckSumIn.byte0]
  RS232Flag = StateTrue
No232:
@ INT_RETURN

I check in main loop if RS232Flag was set, and then do all the processing there.

Thank you Henrik for explaining it well and giving me ideas how to trace the steps the codes is doing.
and thank you Robert for sharing your code...I will try them out.

For sending a string of keystrokes instead of typing and having a delay, as Henrik spoted, try this terminal program:

It can accept a string of characters and then you hit send to send it as it would your GSM device.
