Hello Corinna, I have problems with read() function blocking and waiting for characters on serial line with cygwin:
Here are some code fragments: ======================================================== fd = open(sl, O_RDWR | O_NOCTTY | O_NONBLOCK | O_NDELAY) newpio.c_cflag = brate | CS8 | CLOCAL | CREAD; newpio.c_iflag = IGNPAR | ICRNL; newpio.c_oflag = 0; newpio.c_lflag = 0; newpio.c_cc[VTIME] = 1; newpio.c_cc[VMIN] = 0; ... n = ioctl(fd, TIOCINQ, &n); //It gives me an error (return -1) why??!!! and n = read(fd, buffer, 1); <<< HERE IS BLOCKING!!! ======================================================== TIOCINQ is working on CYGWIN, Is there another way to solve this problem??? Thank you in advance, Ernesto. -- Ernesto PAISER ____________________ [EMAIL PROTECTED] E.S.R.F. - European Synchrotron Radiation Facility 6 rue Jules Horowitz BP 220 Grenoble CEDEX France phone +33 4 76 88 23 48 fax +33 4 76 88 23 25 -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
