I couldnt say :) historically, foundry cli and configuration has been
*awful*.  but, you see in your o/p that term length doesn't actually work,
so it will be paging the o/p, which just makes a mess.

so, complain to the mfg about the speed of the command.  or look for PRs
and subsequently s/w where it is fixed.  also, that may not be it; 4s is
much less than the 90s that francid uses for timeout.

on to the ssh problem, use -t 180 to debug and see where it is failing.  the
full collection commands are (francid -C):

flogin -t 180 -c 'show version;show chassis;show module;show flash;write term;show running-config' hostname
