33 // This module is designed to provide a uniform method of sending commands to
34 // the board through command packets. The difficulty is, some commands take

36 // commands to the same channel as part of the same packet. (See also i2pack.h.)

39 // remembering the exact syntax of each command, or at least so that the
40 // compiler could check things somewhat. I'll explain as we go...

50 	// worry yet how the parameters will be initialized; macros later take care
