1.3.6.1.4.1.2011.5.25.157.1.23.3.1.6
This object indicates the baud rate of a serial interface.
The value can be :
0: 600bit/s, 1: 1200bit/s, 2: 2400bit/s, 3: 4800bit/s,
4: 9600bit/s, 5: 19200bit/s, 6: 38400bit/s, 7: 48000bit/s, 8~38: N*64Kbit/s N<=31.
The default value is 9600 bit/s in asynchronous transmission mode
and 64 kbit/s in synchronous transmission mode.
