Serial Communications Non-Blocking Read etc


Hello,

What is the status of Cygwin under WinXP, non-blocking i/o reads from
/dev/ttyS0 or /dev/com1 type devices?

Writing to the serial port works but I can't get it to not block on
reads and forget about handling a sigaction SIGIO event.

Any ideas?

Cheers,

Steven Henke
