Hi there! Using dev/ttyS0 in my program works perfect, but I would like to use /dev/ttyS1, /dev/ttyS2 and /dev/ttyS3 as well. To avoid any trouble, I assigned a different interrupt to each of the four serial pots:
ttyS0 4 ttyS1 3 ttyS2 5 ttyS3 7 and I used the usual i/o-addresses. All is set using setserial. Then I set uart=none for all four serial ports. Now what is the proper call of rt_com_setup() for these four? I thought the first parameter has to be 0, 1, 2 and 3 according to the digit in ttyS*. Is this correct? The hardware is definitely set up alright, as the board I am using can be jumpered very conveniently to any setting desired. I also tested it in Win98. There COM1 to COM3 worked perfect, just COM4 had a problem, because Win98 refused to use Interrupt 7 for anything but a printer. What do you think the problem might be? How can I use more than one serial port? All I can tell is that rt_com_setup() returns -1. My system: Pentuim 75, 32 MB RAM RTLinux 2.2.18 RT_Com 3.0 Thank you very much in advance for helping!
