except its faded into the sunset. The last .asm cpoy I have is dated in 
2003. I actually have a copy of that, written by Bruce and IT'S FLOW 
CONTROLS WORKED. Both 7 wire and xon/xoff.  No dropped bits. 
Automatically internally named as its a conditional assembly, called 
DACIA if for Bruces dual pak, and SACIA if built for the rs-232 pak.  
And the 7 wire protocol Just Works. And it doesn't work for anything 
later called sc6551. If anyone wants a copy, I'll move a copy of it to 
my web page. IMO it should go back into nitros9 as the default rs232 
pack driver.
