I have two exes that are reading data over the serial port. One is a test serial that tests the reading of the string. They both are identical in the serial com setup but one works and one does not. the obvious would be to say that they are different but they are identical in the serial write/read respect. They both first write "?" over the port to the main vi that when it is read in it sets a case to true that then writes the data string to the exe on anther PC. Both the exes have an indicator of bytes out and sometimes when I run each of them the value is 0. On one of them it does have the write bytes equal to 1 but on the other it always is zero. Earlier today that very exe did work for a while then failed to write, Any idea of this inconsistent visa write?
