serial.device problems

What is wrong with this code:

???

When running it once, it exits fine, nothing happens, but running it a second time in a row makes it go DSI. How on earth can this be??

Apparently it is not allowed to CloseDevice twice, when access is shared. Removing on CloseDevice fixed the crash.

I think the crash is caused by not performing WaitIO() after AbortIO() so the program crashes on CloseDevice() due to the outstanding request.

@alfkil
The note in the AbortIO() autodoc indicates that Steady is right. You need to wait for the reply to an AbortIO request too.

@xenic + Steady

Nope, that's not it, I just tried. Also note, that it doesn't crash the first time through, only the second time I try to run the program.

It must be, that because I'm using the device in shared mode it needs to only be closed once. If that's the case, it is different from os3 and it should be noted in the autodocs, which it is not.
