<1> Control Mode 0 = Front Panel, 1 = Terminal Mode, 2 = Remote Port (Computer RLLP)
<1> Software Revision Binary number, decimal point implied
<1> Number of Channels 10 decimal for RCS20
<1> Number of Status
Bytes Per Channel 3 as of release 1.0, 5 as of release 4.0
*This number of bytes per channel might change with newer release numbers. It is
set to 3 up to release 3.9, and 5 bytes as of release 4.0.
**Remote M&C developers must make use of this value to find out how many bytes
per channel are being transmitted.
