Both of thosed are extremely old. Our ability to help you with them is very limited. Please use the current code.

I searched through the kernel configuration options via menuconfig, i could not find anything that configures the number of serial ports. In LINUX, i tried creating ttyS1 with "mknod -m 660 /dev/ttS1 c 4 65". A /dev/ttyS1 shows up in the directory listing, but I am unable to transmit/receive characters on it.

You want /dev/ttyCPM1, and you should use udev or equivalent to create the device nodes.
