Any idea how I can fix this? The console inside the VM
is quite unusable when it does not have the correct
Not sure how you're getting 'dialup' as the terminal type: the default
ttys file for 10.1 shouldn't need to be edited, and has
ttyu0 "/usr/libexec/getty std.9600" vt100 onifconsole secure
The rows/columns is always 0 for uart-style serial lines since it's
not possible to know what's on the other end. That's why $TERM has to be
set correctly for these.
Having an xterm attached to the other end of an nmdm device isn't too
different from swapping say a vt100 with a vt420 or some other terminal
with a different resolution on a real serial line. There's no way for
the serial driver to know this has happened.
The only way to fix the changing-size problem is to have a
paravirtualized tty device that has a way of reading the terminal window
size and being informed of changes. The virtio-serial specification has
this ability, however, the FreeBSD driver for this can't operate in
polled mode so can't be the main console port, and in any event there's
no bhyve backend for it currently.
Or, you can network-login to the guest in which case xterm works fine :)
