I found the page on the wiki explaining DCD/DSR along with the other flow
control quirks. Once I corrected that, it started behaving correctly.
I'll look into that TPDD Arduino project, since that happens to be the same
platform I'm using for my emulator. It kind of feels like I'm re-inventing the
wheel, but there are some features I'd like to add to my emulator that that
project lacks.
Thanks for all of the extra info! I shouldn't have as much reverse-engineering
to do now.

Sorry guys, but I'm jumping up on the soap box for this one. I'm quite stunned
by this email.
First, there is the official protocol put out by Tandy "Software Manual For
Portable Disk Drive" 26-3808
http://manx-docs.org/mirror/harte/Radio%20Shack/TRS-80%20Model%20100%20Portable%20Disk.pdf
There is a full writeup on bitchin100.com
http://bitchin100.com/wiki/index.php?title=TPDD_Base_Protocol
And if that's not enough there is the TPDD2 sector access protocol writeup
www.club100.org/memfiles/index.php?action=downloadfile&filename=TPDD2-Sector%20Access.txt&directory=Kurt%20McCullum/TPDD%20Client&
To suggest that somehow those of us who have created TPDD emulators are somehow
hiding that information is silly. Ken and John have done a huge amount of work
and documentation and that has been for the 'benefit' of the Model-T community.
LaddieAlpha/mComm/Desklink and more are freely available for the 'benefit' of
the Model-T community. If others want to create a low cost TPDD emulator, I'm
all for it.
We are not hiding any secrets here. Stepping down from the soap box now.
