I am trying to connect a waysmall basix 200 to a box running debian etch with a null modem serial cable, but as yet have been entirely unsuccessful, despite plenty of googling and browsing the wiki :-p

I think I've got the right ~/.kermrc (see below), and /dev/ttyS0 is read/write for everyone. Kermit doesn't display any errors, in fact kermit doesn't display anything after connecting (no login prompt at all).

Connecting the rx and tx lines on the serial port (on the debian/etch box) shows that it is at least tranmitting and receiving, but perhaps the next step is to try the gumstix on different hardware? (not easy for me but possible).

Networking the gumstix over usb is working without a problem.

Could somebody point out what I might be doing wrong, or suggest any further diagnostics. I'm trying to avoid blaming any hardware failure on the gumstix...

As an aside I've also been unable to get either the gumstix or the debian/etch box to receive NMEA output over rs232 from a GPS unit, so at least 2 devices aren't functioning properly for me! (well, it's either that or I'm the malfunction...)

Kind regards,

You could try minicom.  It seems to detect settings much better than kermit.  Just let the gumstix start booting and then start minicom on the debian box.
