On RH6.1 and 6.2 the 'fconfigure' command does not work. So Tcl/Tk
programs using the serial port do not work. You can run my program 'tkusr'
to check the problem.
Some users have reported that running and re-compiling tcl/tk 8.0.x (from a
tcl/tk 8.3.x, on a RH6.2 fixed the problem.
tcktk-8.3. are available in Red Hat 7.0 (and RawHide). The problem does not
impirtant enough to issue an errata for Red Hat 6.x, use one of the suggested
(i.e. recompile from a src.rpm).
Anyway, I does not matter, since It works on Debian :-))))))
(I'm astounded by the lack of professionalism of so called professionals)
