C = invalid checksum
will be a single packet response error.

(
B = Illegal parameter value
D = Illegal ID
E = Data not available
F = Cannot do now (some commands require the Cygnus 2 to be in
Ready/Stop).
L = Length Error, must be greater than 0 and equal to or less than 65,500 bytes.
P = Prior command failed (if one command of a multiple command packet fails,
none of the following commands will be done, and this error code will be
returned).
F = illegal format (The command could not be processed because a byte in the
command packet did not fit the recognized format)
I = invalid message (Unrecognized command in the packet)
M = too many commands (Only 100 allowed)
O = Response length is larger than response buffer
