Qtopia launches pppd without a device parameter and redirects the modem
device through a pseudo-tty to the stdin/out of the pppd process. Qtopia
assumes BSD-style /dev/pty*, but on my FR I only got /dev/pts.

So I patched it for /dev/pts. Not sure how correct I have done this.

Anyway it's not working yet:

Jul 28 16:29:29 om-gta02 user.notice Qtopia: '

we'll see ...
