  Problem is, the VT100 emulation supported by the terminal protocol
converter is slightly different from what Procomm calls VT100
emulation. You could get by using the three character sequence 'ESC O
M' to clear the screen (that's ESCape key, big O, big M) or redefine
some key to do it for you (Procomm v2.42 does not allow this; rumour
has it that Procomm+ does). You'll probably also have problems with
cursors and PF keys. What's needed are escape sequences like ESC O A,
ESC O B ... for the cursors and ESC O w, ESC O q, ...  for the PF
keys. I believe the latter are the sequences sent by a VT100 in
something called keypad *application* mode. If Procomm doesn't let you
redefine the keys to sent the appropriate sequences, your best bet is
to use Kermit v2.xx, which is available from Columbia Univ - it's a
great program, can easily redefine keys, and has built-in TEK 4010/14
graphics emulation.
