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 -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Maintainer cygwin AT cygwin DOT com Red Hat
