Hi Eddie,
You might be better off starting with the fully disassembled version of
TS-DOS and then changing out the TPDD protocol sections with new code to
send out the commands required by the serial USB dongle.
Also, you could probably use VirtualT with serial port host emulation to
connect the emulated M100 COM port to a physical Host serial port and
talk directly with the dongle.

Awhile ago there was a discussion about how a m100 could save and
recall files from a usb stick. The discussion stopped when the issue
of changing file directories came up. Perhaps there is an answer. An
old program on ROM called Disk + used the M100 serial port to transfer
files to a host computer. The host would run a program on floppy that
was equivalent to interserver/interlink of the old days and just sit
there waiting for commands. No further user interaction required.
The major thing about Disk + is that it allows for changing file
folders. This means that a huge library of programs could be
organized. Now, there are also products available that a usb memory
stick can connect to that allow for a serial connection to transfer
files back and forth (however, the usb stick would have to be
formatted on a more modern computer before use). These devices take in
simple commands for creating, updating, and deleting files. Is it
possible to use an M100 emulator and the ROM file of Disk + to 'map'
the instructions that are used for create, update, delete? Then look
at the ROM code and change those commands to match those of the
serial to USB device? Note: Disk+ and the usb to serial devices
allow for changes in baud rates. Thoughts?
