Hi, simply try to remove the backslash from your remark.
charsin=read(f3,anmes,256); /* read message + cr */ -----Ursprüngliche Nachricht----- Von: ROLAND [mailto:[EMAIL PROTECTED]] Gesendet am: Dienstag, 29. Januar 2002 14:12 An: [EMAIL PROTECTED] Betreff: read() on serial port I just can't figure it out... Here is the code of the part that does not work. signal(SIGALRM,alarm_handler); /* set signal handler */ alarm(TIMOUT); /* set alarm */ while(mesan!=SET){ if(progopt==SET) printf("<"); charsin=read(f3,anmes,256); /* read message + \n */ if(anmes[2]=='0'&&anmes[3]=='1') mesan=SET; /* message is ack/nak message */ } alarm(0); /* reset alarm */ signal(SIGALRM,SIG_DFL); /* reset signal handler */ For some strange reason my program just locks on the read(), and then nothing works anymore (not even the signal and alarm). Does anybody have a clue??? The program should try to read an ACK/NACK from the serial port and if it did not read anything within 10 secs, it should trigger the alarm. Please help me with this, I don't know what to do anymore. Roland __________________________________________________ Do You Yahoo!? Great stuff seeking new owners in Yahoo!
