In my opinion just desynchronization - that it program waits for data which are never received, because of some error in transmission before. Really, try strace. See http://crds.chemie.unibas.ch/PCI-MIO-E/pcontrol-parport-balzers/balzersd.c See read_t() - read with timeout function for serial port. You need to take care that loss or change of single character can be recovered. The program must have ability to reinitiate transmission if data not received or corrupted. -- Tomek -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl <Your_email>" | mail [EMAIL PROTECTED] --- For more information on Real-Time Linux see: http://www.rtlinux.org/rtlinux/
