This actually looks ok. I *thought* it would be sending the 0x0a,
but it doesn't in my set up.
Try turning on physical logging (as above) while doing a manual chat.
You'll see that the characters actually being transmitted are the
same.... if they're not, that's the problem :-/

0x0d is a carriage return (the <-- key)
0x0a is a linefeed (^J)

All send strings are assumed to have a 0x0d at the end *unless* the
last bit is \c.
It's interesting that if you specify your send string ending with \n,
ppp sends 0x0a 0x0d rather than the more conventional 0x0d 0x0a ! I
must fix that !

Comparing the ``physical'' logs is probably the best step next.
