Pmw.ScrolledText

[Donald L. Dietmeyer]

I am attempting to put together a "dumb terminal"
using a Pmw.ScrolledText to communicate via a
serial port with a box that does the echoing of
characters it receives.  How can I stop the ScrolledText
from echoing characters typed to it?  Or lacking that,
how can I know when a character has been echoed so that
I can write a backspace to the displayed text?

Maybe there is a better widget for this application?
