I have an application that has strict timing.
Inter-character delay must be no more than is 0.15s
The messages themselves are quite small. 10 - 50 chars
I don t understand what ReadTotalTimeoutMultiplier and ReadTotalTimeoutConstant actually mean in practice.
The math in this example doesn t work? http://www.lookrs232.com/com_port_programming/api_commtimeouts.htm
