[tor-dev] Tor Control Protocol: multiple commands in a single line possible?

[Tom van der Woerdt]

Hi Patrick,

No, the protocol does not support this. The only command separator is a
newline. Implementing this would likely be hard anyway, as the output of
the double command would be hard to parse.
