This is as it should be. It was done because of a shortcoming in the VGA
architecture. The color assignments are changeable at compile time in
pcvt_conf.h.

This is as it should be. It was done because of personal prefenrence and
is cahngeable at compile time in pcvt_conf.h.

No idea, never used IRC.

You seem to be as very fast typist then ! :-)

The cursor update is done asynchronously in pcvt and its frequency is 
controlled by the compile time variable PCVT_UPDATEFAST which is again
changable in pcvt_conf.h.

No idea. I'm using bash for years now, and it works for me.

For your items 3 and 5: perhaps you want to switch pcvt in the HP mode
(scon -H) in which you can toggle a display functions mode by pressing F8.
In this mode escape sequences and control codes dont get executed but dis-
played, so it might be possible to find the cause of these problems.

Anyway, i would also suggest to read the (not perfect) docs in the directory
/usr/src/usr.sbin/pcvt/Misc/Doc !
 
Hope this helps,
hellmuth
