[Cu-wireless] Seial PCMCIA for Soekris 4521?

[David Young]

I think the 4521 actually has a second serial port, but it is missing
line drivers and a jack. But if there are not solder pads for those parts,
you won't be able to use it very easily.

If you're really ambitious, you could attach a serial UART and line
driver to the GPIO header. And then you could write a driver. What fun
you will have! =)
