Hi.
I am trying to output to a serial port , but I get an error message. Uisnf a serial Port analyser, it says the serial Port has lkaready been open by another app, but I cannot identify which app, and there is'nt anything obvious running which uses the serial port.

Anybody know of a way of identidying which process has the serial port open, or is there a way of closing the serial port from a different app ?

Regards,
Gerard
