a problem with the KW-531A boards (of which i currently own, i think
4, at last count, one of which is handling this SLIP connection... 8-)
is that you can only set them for IRQ 3 or IRQ 4.
given the way multiport boards "want" the UARTS set up, as i
explained Guido, it's relatively hard to use a UART w/the
standard support circuitry at the same time, w/o beating on the driver.
what this tranlates to *i* just disable the normal UART on
whichever IRQ i want, rather than make the driver that much uglier.
(or course, i've got lots of spare ports these days... 8-)
