Dear all, excuse me again for a newbie question. Environment: Pentium 166 MMX, RTAI 1.5, RT_COM 0.5.4 (all system modules compiled and installed properly). I'd need to use just one serial in hard realtime mode, while the other would be used by a prog in the user space thru termios.h . I modified a bit the testcomrtai.c in order to send periodically a string ("A\r\n") thru the "hard realtime time serial port". *Before* running the serial RT module, I reconfigure the serial with "setserial /dev/ttyS1 uart none". Well, after all this have been carried out, everything seems running alright, BUT if I check on the RT port with an oscilloscope, nothing seems happen (while the termios port is working properly). Every hint will be greatly appreciated ;-) Thank you in advance Paolo _____________________________________ Paolo Meriggi, Ph.D. student Dept. of Electronics for Automation University of Brescia Tel. +39-30-3715456 Fax +30-30-380014 http://www.ing.unibs.it/~meriggi _____________________________________ -- [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/
