ASCOM and multithreading

[Horia]

@Chris

ASCOM drivers should be thread safe. The hardware probably isn’t, usually the problem is that a second serial command is sent before the reply to the first one is received.

The simplest fix is to call the same function for all serial commands and put a lock round the transmit and receive functions so if a second call to the hardware is made it blocks until the first one has completed.

Thank you Chris, this is exactely how I solved it. I guess the most important was to understand that thread safety is required.

Kind regards,
