Ah-hah, got it. I had to handle this stuff for Axim as well. I've added
the required cable detection stuff to h2200.c, however I'm not sure if
the signal I've used for cable detection will work. Can someone check
with HaRET if the following really works:

a) First turn off the power to RS-232 transceiver. For this, issue a
"SET GPLR(80) 0" command.
b) Now print the state of the GPIO4: print "%d" GPLR(4). This should
give you a 0 if the serial cable is not plugged in.
c) Finally, if you plug in the serial cable, you should get a '1' from
the previous command.

If all this works, its ok. If it doesn't, just comment for now the
SET_H2200_GPIO(RS232_ON ...) lines, and set GPIO80 default state to 80.

Grmpf.... it looks like both MediaQ needs space for IRQs (about 20 IRQs)
and the HAMCOP chip also needs this space (don't know how much). By
default there is space for 48 extra IRQs, so if HAMCOP is using more
than 28 IRQs (46 to be exact), that's the cause.

I've increased the IRQ_BOARD_END constant, now it should be enough.

He just didnt loaded the shamcop driver.
