there are a bunch of vt/screen manipulation code in the o/p.  this is
probably the issue that you're facing because it makes a mess for
regex matches/etc.

you can try setting the terminal type to something that doesnt support
it (like agmrancid), which might cause the device to stop sending this
junk or try hlogin (or adapt it) to filter it out.
