All:

I am having difficulty installing my mainpine rockforce octo+ and
configuring Fedora kernel 2.6.5-1.358.i386 serial ports/ttyS latches. I have
the following information:


We have recompiled the fedora core 2 kernel with the options for multiport
serial devices enabled as suggested earlier.

We ran the setserial command:
setserial /dev/ttyS14 port 0xdc80 irq 9 autoconfig ^fourport substituting
apropriate io addresses and ttyS where apropriate

we are still getting "Cannot get multiport config: Invalid argument" after
running setserial /dev/ttyS14 set_multiport port1 0xdce0 mask1 0xFF match1
00x00




You may have to recompile your kernel with the multiport options enabled.

Chris/Lee,


In kernel-2.4, the multiport 'latch' is required. Most major distros default kernels are compiled with multiport support, and so the set_multiport line would execute properly (at least when there's no ioport interrupts) and a kernel recompile would not be required.

This has completely changed in kernel-2.6 ... they've reworked the multiport serial support quite a bit.

We've been working with Mainpine to help them develop a recommended configuration procedure for kernel-2.6, and we each have 2.6-based fedora's in our labs in testing. So far, it seems like you can run all the setserial commands _except_ for the multiport latch (which is not relevant to kernel-2.6 and as far as we can tell will never work) and it should 'just work'.

Look for an update on Mainpine's website once they've finalized their official recommendations.
