HELP !! Is there any special thing I need to do to have a rt process respond to a COM1 IRQ ? I am using COM1 with a 16C550 chip and I can send and receive data in polled mode no problem. But, if I try and use my rt_process -- insmod that sets up the port then enables the irq and defines a handler, it does not respond. I proved to myself that if I add a parallel I/O card at IRQ4 and generate and IRQ for this card, the ISR is entered. I figure maybe I am doing something wrong enabling the IRQ's for the 16C330 chip, but looking at the registers it appears to me that all I need to do is set bit 0 of the Interrupt Enable Register when DLAB=0. I'm on RTLv1.1 kernel 2.0.36 -- THANKS IN ADVANCE Janet Estabridis Electrical Engineer NAWC Code 473E00D Building 31440 Room 1017 China Lake, CA 93555 [EMAIL PROTECTED] (760) 939-2896 FAX (760) 939 -3075 --- [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/
