I have a problem using my serial ports with Xenix 386 2.3.2. I have a standard dumb com4 card with no polling register. The card can use IRQ lines 2,3,4,5. I have managed to use 3 of the ports by assigning them to IRQ 3,4 and 5 and by editing my master and sioconf.c file. But I cannot enable the fourth port. Is there a way to let two of the ports use the same IRQ line and making an entry like this in the sioconf.c file: {0,IBM_BOARD, 2,4,0, (sd)0x3e0,0, 8,MCRBIT3} When I do this Xenix finds the ports in the boot sequence but when I try to write to the port the task hangs until I press DEL. Nothing gets written to the port. Please answer by email. Thanks in advance for the answers I get -- ------------------------------------------------------------------------------ Ivar E.
