 locking up sounds like broken BIOS code, have you tried booting with
a fix? (put it before MiNT!)  especially flow control just seems to be
impossible for atari to implement properly, and if your unlucky this
_can_ leave your tty in a `hung' state...

 i don't know about modm0dev (it only works on modem1 and modem1 is
too slow for my modem :), but to get signals working you can also
go thru a pty i.e. use anything like script /dev/null, telnet...
or just screen -fn if you have enough RAM.

 not included but surely available?

 the simplest solution is just have the user say something like
`script /dev/ttyv9', this also has the advantage that he knows
big brother is watching him :)

 of course as soon as he changes TERM you'll have a problem...
