lirc.conf parameter to control space between codes

[Tom M. <tme...@gm...>]

When irsend is executed with parameters like:

% irsend SEND_ONCE remote KEY_1 KEY_2 KEY_3

what parameter in lirc.conf specifically controls the pause between the
transmission of KEY_1 and KEY_2?

'gap' seems like the obvious answer, but experimentally it doesn't seem
to do the trick. Some information I've seen suggests that 'gap' might
control the spacing between the initial code and the repeat code when a
code is being sent repeatedly, which is not necessarily the same thing
as the pause between different codes.
