I'm making a menu driven datalogger and am having trouble with hyperterminal not showing all my menu items. If there are only a few lines, everything displays with no problems. but if certain additional menu items show up then the last line of my menu only shows some characters or not at all.
if the "MEMORY CONTAINS DATA" OR "TURBINE IS DE-ACTIVATED" gets displayed then the last line shows:

HOLD (A) while LOGGING re

instead of

HOLD (A) while LOGGING returns to this menu

I know with hyperterminal and realterm I have 20 lines by 80 characters so I can't figure out why my menu doesn't fully display.... I cant add any more menu items as they simply dissapear. I'm under the 500 character buffer limit so It's not that.

I start be sending 27,91,50,74 ' this is the ansi esc[2J to clear the buffer
This clears the buffer and screen, then I send 8 lines to hyperterminal for my menu items ( around 400 characters but below the 500 char buffer) each line is terminated with ,13,10
if I try adding more menu items hyperterminal simply wont display them. The text only fills the first 1/4 of hyperterminals windows so lots of room for more.

Thanks for any insight!!
