Which comms program do you use? I use kermit to talk to a VAX running VMS
and I too get the 24 line problem. My guess was that it was probably kermit
which was at fault.

Have you also tried sending ctrl-O to the VT? (can be done by ^Q ^V ^O if
using BASH) This fixes some problems, but not the 24 line problem for me.
Actually, I can live with a 24 line VT. Unfortunately, what I see is
in effect a split-screen VT: one window of 24 lines and one of 1 line.
If the cursor moves into the one-line window at the bottom of the
screen then it tends to stay there (some programs, such as emacs can
still make use of the whole screen). A 1-line VT is very difficult to
live with!
It is my guess that the real problem is a bug in the kernel terminal
code. There may be other problems with this code, for example there
appears to be a bug in the code for the "do" command.
