/proc/interrupts does NOT list all supported interrupts. It just lists the ones that have actually been used. If the lack of a listing here is the ONLY reason why you think your Linux kernel is not supporting the second serial port, then you are probably mistaken. If you have some other reason for believing that ... like you actually tried to access the unidentified "piece of hardware" on the second serial port and failed ... please describe in more detail what the hardware is, how you tried to access it, and what went wrong. Maybe we can help, but not if we don't know what the actual problem is. In any case, a linx kernel may or may not have serial-device support installed (either compiled in or insmod'ed). But it isn't selective. At 11:30 PM 8/7/00 -0400, Peter Howell wrote: > My question is simply how do I get it to work. Here what info I have. > >I recently reinstalled Caldera Openlinux 2.3.
