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?
