This is the patch pack that should add interface_signal() and bitbang() functionality (binary backend + tcl frontend) to the interface API + example implementation for FT2232 interfaces (layout independent).
Patches can be applied on top of the current GIT HEAD. Please verify
their functionality as this is result of stripped patching from my
work-in-progress-fork.
The example usage is following:
%telnet localhost 4444
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Bad syntax!
interface_signal (add|del|list) signal_name [mask]
in procedure 'interface_signal'
