This is a client-side tool for sending files to a CP/M machine attached on a serial port. It assumes Unix/Linux behavior, so probably doesn't work on Windows machines outside of WSL. For Windows you can use Grant Searle's binaries available here.
This uses Grant's DOWNLOAD.COM program on the CP/M side. If you do not have
this pre-installed, you may find a CP/M binary in this repo in the 3rdparty/
directory. This version is slightly modified, but either will work.
If you are running an RC2014 and using Spencer's original distribution of CP/M
on CompactFlash, then the default location of DOWNLOAD.COM will work for you.
Otherwise, you will need to pass it on the command line. The following options
are available:
Options:
-d, --download-path=<s> Path to DOWNLOAD.COM on CP/M (default: A:DOWNLOAD)
-f, --file=<s> File to upload
-u, --user=<i> The CP/M user ID to upload to (default: 0)
-p, --port=<s> The path to the serial port (default: /dev/cu.usbserial-FTDOMLSO)
-s, --serial-speed=<i> Serial port speed (default: 115200)
-h, --help Show this message
Note that the serial settings assume 8-N-1 behavior. If you need to do
otherwise, you may configure them in the source of the program. since this is
how 99% of terminals will be set, I did not break them out.
This works great on my macOS machine running at 115200. It works just fine with
minicom running in another terminal as well.
Note This assumes that RTS/CTS hardware flow control is available on the serial line.
You only need to have Ruby installed (most systems do already). Then just run
gem install bundler if you don't have bundler. Then bundle install. Then
you are ready to go.
You will want to have already gotten the serial port into a session on CP/M and have it sitting in the path where you want to upload the file. Make sure it's at a clean command prompt. You may then invoke it like this from another terminal window:
./upload.rb --file <file to send>
You should see the output echoed back from CP/M and then an OK at the end.
