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:
