Serial input message/trigger?

[Boris]

I have used with great success modified versions of the commexample programs. (TY Paul). Is there a windows message sent when the serial input buffer receives a byte, or is not empty? A message I can test for in my window service routine? Like:

If @class=@serintrig then gosub get_data_from_serial_input_buffer

The idea is to have my external microcontroller send a byte at irregular intervals and the EBASIC serial receiving routine only react on reception of a byte (without polling).

The program I am using now just polls the microcontroller once a second, sending a â€ËÅ"go’ code then collecting the data sent from the microcontroller.

Any ideas?

The WaitCommEvent function seems to be what you're looking for.
