On Linux isatty on a descriptor connected to serial line returns 0,
on Cygwin it returned 1 so far. I fixed both problems here, isatty
on a serial line returns 0 now, and lseek on serial (and, FWIW,
sockets) don't simply return 0 anymore, but rather -1 with errno set
to ESPIPE, as on Linux.
These patches are available in the latest snapshot I just uploaded
to https://cygwin.com/snapshots/
Ross, please give it a try.
Thanks,
Corinna
