RE: [Xen-devel] mingetty on console on demo disk

["Barry Silverman" <barry@xxxxxxxxx>]

The problem seems to be that xend doesn't support enough of the telnet
protocol to force the connection into "character mode". At least on my
system, telnet is going into "obsolete line-at-time" mode that has these
nasty interactions like locally echoing the whole command line, trapping
control characters, row wrapping, ....

When I give the telnet escape, followed by the command "mode character", it
behaves much more rationally.

I believe you can work around the problem by having a .telnetrc file with
the "mode character" command in it, but the proper fix would be to a) have
xend give the protocol sequence to force the telnet client into character
mode
or b) use some simpler home brew client that doesn't try to use telnet's
fancy local processing.

It's not xend that's the problem, but something in the tty driver
in xenolinux. To be honest, we can't make head nor tail of the
Linux tty code, and have no idea why resizing etc doesn't work.
We're probably just not setting some parameter some
where. However, we appear to be 'bug compatible' with using a
serial console on RH9.

Perhaps someone on xen-devel knows about tty's and could take a
look ???

That won't effect things, as xend is just an 8bit clean pipe.
