Alright! So at this point, my emulator can perform all of the basic TPDD
file access functions pretty reliably!
Loading TS-DOS.CO off of the disk provided the perfect test. Any faults and
it will lock up or throw some kind of error. After 10 read/write/read
cycles, TS-DOS has started every single
So far, I haven't had any issues with delay. At the moment, my emulator
works with TS-DOS up until it starts reading data from DOS100.CO (because I
haven't implemented that part yet!). I did notice that it sends multiple
requests one after another, which will require me to revise my command

The TS-DOS delay issue will be your biggest problem. For testing, you
may want to load the TS-DOS or SARDOS ROM that I put together than has
more delay built in. By default, TS-DOS waits for 3ms before if tries to
switch down to 9600 baud. It's all part of the directory support that
was added for D
Hee hee,
Yeah, if you want some C++ code, just look in VirtualT:
virtualt/src/tpddserver.cpp
virtualt/src/tpddserver.h
Not sure how I can be more open than that.

Hello Jimmy,
I'm the author of LaddieAlpha, and I maintain DLPlus. You are welcome to
look at any of that source to understand the protocol.
I haven't had any issue with flow control. Set DSR and CTS so that
unpatched TS-DOS "cable detect" insanity is satisfied. Set baud to 19200,

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
