I was trying to use your program to control power on a Motorola QIP-6200.
 Using the "off" command causes to power state to invert.  Using the "on"
command has no effect.   Do you have any suggestions?

"sa3250cmd -v -n 0 on" produces this output:

Sending Command: 0x00FB270
Success, Response: 0x09FFB270
Sending Command: 0x01FFB27F
Success, Response: 0x0CFFB270
return code: 2

But the STB doesn't change power state, whether I do it when the power is on
or off.

"sa3250cmd -v -n 0 off" produces this output:

Sending Command: 0x00FB260
Success, Response: 0x09FFB260
Sending Command: 0x01FFB27F
Success, Response: 0x0CFFB270
return code: 2

And switches the power off it is on, and on if it is off.
