The man page for pppd says:

NAME
     pppd - point to point protocol daemon

SYNOPSIS
     pppd [tty_name] [speed] [options]

but nowwhere does it say what speeds are aceptable. If one puts a
speed it does not like, it default to 9600. But whilst 9600, 19200 and
38400 work, I've got no idea what (if any) faster connections are
possible. I only found them by trial and error - nothing is
documented.
