been detected. When the sub-command code is 'R', the sub-
command parameter 'Y' must be either 'A', 'E', or 'P' (for
azimuth, elevation, or polarization respectively) to specify
which axis will be reset. If the 'P' command is specified, the
command will be accepted only if the RC2000A is configured
for use with the optional rotating feed.
'X' = 'P' This sub-command allows the host to enable or disable the
AutoPol mode. If the sub-command is 'P' the sub-command
parameter 'Y' must either be 'N' or 'F' (for AutoPol oN or ofF,
respectively).
'X' = 'Q' This sub-command can initiate an immediate peakup
operation. A sub-command parameter of 'C' initiates a C band
peakup. A sub-command parameter of 'K' initiates a Ku band
peakup. This command will be accepted if the controller
supports peakups, if the controller's Peakup Enable CONFIG
mode item is enabled, the Peakup related parameters in non-
volatile memory are valid, and a peakup is not currently in
progress. Otherwise, a NAK reply will be sent to the host.
'X' = 'K' This sub-command sends a keypad value to the RC2000 (this
is referred to as key-stuffing). The RC2000 will react to the
keypad value as if the corresponding key on the RC2000's
front panel was pushed. The command is implemented using
the miscellaneous command format.

Antenna jog operations are controlled by the length of time that
a jog key is depressed by the user. To emulate this
characteristic when jogging the controller with the
Miscellaneous keystuff command, the reception of a
Miscellaneous keystuff command initiates a timer. The key
