Posted: Wed Jun 27, 2012 2:48 pm
Where can I find information about RS232 timeout. What is the meaning, what are realistic/advised numbers?
Kind regards

Hi Jan,
There are two settings for the timeout available from the RS232 component properties.
Legacy - Timeout is based on a number of iterations, delay is clock speed dependent.
Millisecond - Timeout is based in milliseconds, delay is clock speed independent.
If a byte is received during the timeout period then the macro will return immediately with the data.
If a timeout period of 255 is used then the macro will wait forever for valid data.
This info applies to both hardware and software UARTs.
