From my guide:

seta
Usage : rcon seta [variable] [value]
Sets the value of a variable and the archive flag so that the value will be saved to the user's Default.cfg file to be loaded each time the game is loaded.

sets
Usage : rcon sets [variable] [value]
Sets the value of a variable and the server flag so that the variable is transmitted to clients upon connect. Is implemented in MoHAA but does not seem to function properly.

setu
Usage : rcon setu [variable] [value]
Sets the variable with the userinfo flag, so it will be transmitted from a client to a server while connecting.
Caveat : Not tested, however I suspect that like sets , it is not functioning properly.

You may want to look up the standard quake commands. Most of the basic video commands do the same thing. They may not have been documented via MOH but I'm sure someone has done this for Quake.

good luck
