I am setting up a system that uses PPP to dial out to a
server.  To dial out through the PBX at that location, you
must dial a "#" first.  This character is a comment
character to the "chat" program if it is at the beginning of
a line, but not anywhere else on the line.  However,
linuxconf cannot handle the "#" in the dial string.  If I
put it in and save the interface and then go back in to the
interface configuration screen, the dial number is empty
(like linuxconf sees "#" as a comment anywhere and tosses
it).  It looks like linuxconf does not even save the dial
number; if I go in and manually edit
/etc/sysconfig/network-scripts/chat-ppp0, it just has a line
like:

'OK' 'ATDT'

and I have to manually put in the number to dial.  If I go
back in to linuxconf and do anything to the interface I have
to again manually put the number in.
