Hi Rob,
Thanks for the suggestion but unfortunately it didn't work.

There was a change to ftdi_sio at 2.6.36 that erroneously set the wrong
hardware flow control state when flow control is turned off. It's been
fixed since, but I don't know whether that was included in the first
2.6.38 or whether it was patched later. I did a nasty kludge of calling
ioctl ( SerHnd, TIOCMBIS,&value );
as a work-around when I ran up against this.
I tried all combinations of DTR and RTS with the TIOCMBIS ioctl and
nothing made any difference. I also tried upgrading to 2.6.38-git9 and
that didn't work either. In both cases, the following message is written
repeatedly to the log and read doesn't return.
Mar 21 20:19:45 stomp kernel: drivers/usb/serial/ftdi_sio.c:
ftdi_process_packet - port 0
Any other ideas?
Cheers,
Steve
