That's the result of a Device-Status Report.
https://en.wikipedia.org/wiki/ANSI_escape_code#CSIsection, see "DSR" or "CSI 6n"
39 88 is the size of your terminal, or the one that Kermit is emulating for you.
(I seem to recall think that kermit has a full-screen mode. So many different
versions of it over the decades)
You may be able to turn kermit responding off, or change it's terminal type
to dumb.

The shell is emitting ESC [ 6n to set the stty size of the terminal.
"resize" does this, but I think gnureadline does too.
