The last couple of times I had LCP timeout, I had to run setserial to
make sure the serial port and the rest of the system had the same idea
of what was there. In particular, I used almost the same as the default
parameters, but added the spd_normal and skip_test, plus specified
specifically the 16550A uart. Note that "setserial -a
/dev/whatver_the_modem_is" will give you current settings.
