"""fake_ruida.py: a stand-in Ruida controller on 127.0.0.1:50200 for dry runs.
|
|
|
|
Logs every command it receives (unswizzled hex) to the .log file, ACKs, answers the status and
|
|
document-name reads the way the real controller does (no reply past the last file), and adds
|
|
uploaded file names to its list. Pass "busy" to report a running job so you can watch
|
|
rdupload.py refuse. Test here first; never point untested code at a real laser.

usage: fake_ruida.py [busy] fake.log
