Eterm is a vt102 emulator, not a vt220 emulator.  It does not support
the 8-bit version of the CSI.  You can test this using:

  echo -e "\23321t"

You'll get that exact same string in reponse.

It may be supported at some point in the future, however, in which
case it would be considered a control character just like any other.
