Setserial reports that the ports are ok:
On laptops, 25-pin ports tend to be parallel, rather than serial. At least, that's my experience. [snip] > but minicom or other serial line communication utils do not send or receive > any chars. Any ideas? Hook a printer up to the 25-pin port (the other end of the cable will most likely have 36 pins), then use (I think, it's been a while) /dev/lp0 as your console device, rather than /dev/ttyS#. This assumes that your kernel has parallel console support compiled in, and that the parallel port support is compiled in (as opposed to being a module). And if you do the above, make sure to have lots of paper handy. Also, this trick probably won't work with all printers, but it stands a good chance of working. -Barry K.
