Hi,

I've thrown out most all of your code! My code example replaces everything (it still needs port initialization). Under the assumptions I made (master-slave operation, PC sends command then peripheral replies), there is no need for events, secondary threads, Invoke, etc.

If you can't turn your peripheral into a slave, which would mean it can still send results whenever it likes, then you need more of your code, however even then a delay could save your day: put it anywhere between the start of the DataReceived event and the line that holds SerialPort.ReadLine; this would guarantee (actually increase the probability) that an entire message up to and including newline is present in the serial buffer when ReadLine gets called. However now the delay also increases the probability that you would loose a message, so it makes sense to opt for a shorter delay (I would at first not go below 20 msec though).

Smile | :)
