Thanks for the offer Pat, but I'm not sure it would do anyone but me any 
great amount of good.  That machine is a TRS-80 Color Computer 3, running 
what os9 has been developed into by the community since Radio Shack 
discontinued it 20 years ago.

FWIW, here is an xmode report on that port that minicom is talking to:

{t2|07}/DD/MAXTOR/RIBB:xmode /t2   
 nam=t2 mgr=SCF ddr=sc6551 hpn=07 hpa=FF68 upc=00 bso=01 dlo=00
 eko=01 alf=01 nul=00 pau=01 pag=18 bsp=08 del=18 eor=0D
 eof=1B rpr=09 dup=01 psc=17 int=03 qut=05 bse=08 ovf=07
 par=01 bau=06 xon=00 xof=00 col=50 row=32 xtp=02 wnd=02
 val= sty= cpx= cpy= fgc= bgc= bdc=

Some of that is obvious, although I see that alf is not (I don't think) 
correct & probably should be 0A so its a line feed.  I think I have that 
translation setup in setseriel or possibly minicom.  pag=24 lines it pauses 
if pau is non zero.  That machine does not have a screen scroll back 
buffer, so its nice that minicom does.

The values above are hex, and I'll have to look the rest of them up to 
decipher them correctly.  I'll try to do that, but lets not do this on 
Christmas Eve.

Thank you and enjoy the evening and tomorrow.  I will take a look at the 
links above, but no promises.  I know just enough C to be dangerous, most 
at home with assembler code, written for the Hitachi 63C09 that is in that 
machine for a cpu now. It is a much improved, cmos version of the MC6809E 
moto chip.
