I assume you're running 1.1.

Use ttym* for dial-in and tty0* for dial-out.  The driver only supports
8-N-1 for now.  It can auto-detect the UART clock speed, so you can
double the clock to get 38400 bps on the A2232 ports.

I'm not sure if the latest bug fixes have been accepted now, but the
driver in standard 1.1 has some problems with carrier detect handling.
I fixed those bugs well before 1.1 was frozen, but the gurus didn't
include the new version in the tree (dunno why).
