immediately after log-on wait for a 'esc[0c' code sequence from the
remote (or it may send 'esc[c' they are the same request) then reply
with 'esc[?1;0c' to indicate that a VT100 terminal is calling.
Of course don't include the quotation marks or take the 'esc' bits above
literally, 'esc' represents the escape character (Chr(27)).
I hope this helps
