David,
You're a life-saver! AysncFile methods have no trouble reading and
writing from a properly configured serial port. Just set up the port
properly with stty and it's no sweat.
It's especially useful to be able to designate /dev/ttyUSBx for a serial
port that is connected through USB instead of the old RS232 ports.
I'll do some further tests of timing and blocking but just wanted to say
THANKS!!
