[LINUX5250] cursor placement rules

["KJ P" <kjpou@xxxxxxxxxxx>]

I would not exactly say that it was broken per se.

What I found was that there really was no difference in the two.  If you
take a look at the routine processCC1 there is a comment there for reset
blinking cursor code.

I was treating the two commands seperate but after reading dump after dump
after dump and those bits it was easier to do it the way that it is existing
now.

Sometimes trying to translate what the manual says and then look at what is
coming through on the line is confusing.  I never did figure out the meaning
from the manual but those little bit settings in processCC1 method helped me
to get it to work like client access.  Well at least what I mean is that I
have no one that has reported it to me.

There is one problem that is pending in the cursor positioning that I really
need to get around to fixing and that is for GUI windows which turns out to
be another bit setting.  Those bits creep up everywhere.  It is a little
different cursor positioning than the regular screen.  I know where it is
just need to fix it.

I have not looked at the code in the TN5250 for a little over a year so do
not know if it has it in there.  You might want to try that to see if it
helps.

Great emulator/work you guys.  Keep it up.

Regards


Kenneth
