For example：
:SBUS:RS232:BITorder LSBF
set RS232 byte order as LSB
:SBUS:RS232:BITorder?
query return LSBFirst
:SBUS:RS232:SOURce
Command format：
:SBUS:RS232:SOURce { CHANnel1 |
CHANnel2 |
CHANnel3 | CHANnel4 }
:SBUS:RS232:SOURce?
Functional description：
Set encoding source of RS232.
Return format：
Query return{ CHANnel1 |
CHANnel2 |
