Daniel Ritz <daniel.ritz AT alcatel.ch> reports:

ssh client sends a wrong all-zero terminal info when requesting forced
pseudo-terminal allocation while stdin is not a terminal. sshd then
sets the terminals ospeed to 0 because it receives this information
from the client. on solaris this means that the pseudo-terminal is
closed and output of any remote command is dropped.

I think there is a related bug in connection multiplexing too: it looks
like we incorrectly reuse the ttymodes from the master's stdin rather
than picking it up each time
