Hello,
I'm trying to do some serial port communication using NSFIleHandles.
I've having a lot of trouble consistently getting data from the device
I'm communicating with. I'll frequently get maybe a single packet of
data, and subsequent calls to availableData result in a "Resource
temporarily unavailable" exception being thrown. Admittedly I'm pretty
new to serial port communication in this capacity. What trees do I
want to start barking down to debug this issue? Also, what would cause
me to have to scrap using NSFileHandle and use CFSocket APIs?
Cheers and thanks for any advice
Rob
