I pulled what I could find yesterday, but need to make a 25' cable & don't 
have the foggiest about the pinouts.  Since mark doesn't even show it on his 
pages, I don't know where else to look.

I finally managed to make it (sc6551.dr) hang with the rx buffer drained by 
rz this afternoon, but my flow control attempts are pointing at a bad mc1488 
in my rs-232 pack, and its the bottom one in the stack since that pack is 
piggy-backed for 2 ports.

Up till now, the hang has somehow disabled the reads too, leaving the rx 
buffer full, so the DTR wasn't even being brought back true.  I'm still 
analyzing both the codes last listing and the dmem of the drivers memory 
area.  Somewhere the light will come on, but first I need to acquire more 
mc1488's that actually work 100% instead of 99% of the time.  I swear, that 
is the least dependable chip ever designed.

I seem to be more limited in the creative juices dept as the years go by and 
if I can't find a given problem in a couple of hours, I may was well hang it 
up till I've had a chance to sleep on it again.  Getting old is definitely 
not for wimps.
