Yup, been there. Look after the signature for various fixes.
Some of this came from suggestions from GCG and some is local.
No warranties, of course. You may pass this stuff around freely.

SAF_NOTES
11_NCSA_Telnet/MacIP
As some of you have pointed out, these public domain terminal emulators may
or may not work correctly with the GCG editors Seqed and GelAssemble.
(Even though they appear to work correctly everywhere else).
The following commands should fix the problem with the cursor keys:
$MacIP (If you are using MacIP4)
or
$NCSA (If you are using NCSA Telnet)
If you put one or the other of these in your LOGIN.COM you will be
automatically set up to use the corresponding emulator. Only do this
if you ALWAYS use the same emulator.
(If you don't know what an ASCII is don't bother reading the rest of this.)
If you STILL have problems, you may be able to figure out what is going on
by using the (new) utility GCGTERMTEST. This dumps either the ASCII
strings sent by the terminal or the internal GCG key codes that represent
them. Hit the problem keys on a known working emulator, then repeat the
experiment on the problem emulator. This should turn up either that the
emulator is generating the wrong ASCII strings, or that the GCG program is
misinterpreting them.
