I got my gumstix a while back, but ws so busy to play
with it. Today I stayed home sick, and thought it was
the perfect time to play with my new gumstix.
I enabled the serial port in BIOS, installed ckermit
on my laptop running SuSE 9.2, started kermit and set
it to 115200, no parity, no flow control, 8 bit and 1
stop bit, and connected.
Then I plugged my null modem cable that I bought from
gumstix into my laptop and the gumstix, plugged in the
power supply, the little green light came up and I
felt my heart beat a bit faster.
I turned my head anxiously towards the screen to see
what is happening on the kermit console. And there was
I tried to restart the gumstix, verified that I'm
connecting to the right serial interface (/dev/ttyS0),
and all seemed ok.
Is there something else that I should try? or should I
just send it back to gumstix and declare it defected?

Are you sure that your temrinal software is running? Some software
requires you to connect first (I'm not familiar with kermit, so I
can't offer any advice on that.
Unfortunately, it can be hard to tell if the gumstix is really dead.
Which serial port (on the gumstix) did you plug your cable into? The
console is the one towards the middle of the waysmall.
To test out your terminal software, unplug the serial cable from the
gumstix. Use a pair of tweezers or similar and short out the Rx & Tx
lines. If you hold the cable so that the pins are facing you, and the
flat part is up, then the Tx and Rx pins are the two outside pins in
the middle row. If you short out the Rx & Tx lines, and then type
characters in your terminal program you should see them show up as you
type. If you don't see any characters, then you need to fix your
temrinal software, or cable,

several things you could try/check.
- My IBM-notebook had its serial-port disabled by default... (don't ask me
why). Dave Hyland's method of short-cutting the RX and TX should give you a
hint, if your serial port is actually working or not.
- You could try to connect using the USB-port. Even if your Suse doesn't yet
have a recent kernel, you could always try an lsusb, to see, if the gumstix
is correctly registered ("usbview" should do the trick too).
