Caution
When the parameter has been set, a power down or software reset
(using EX) must be performed for the complete system. Not doing
so may result in undefined behaviour.
Type System command
Syntax SET_BIT(bit_number, vr_number)
Description The SET_BIT command sets the specified bit in the specified VR variable to
one. Other bits in the variable will keep their values.
Arguments • bit_number
The number of the bit to be set. Range: [0,23].
• vr_number
The number of the VR variable for which the bit is set. Range: [0,1023].
Example No example.
See also CLEAR_BIT, READ_BIT, VR.
Type Communication command
Syntax SETCOM(baud_rate, data_bits, stop_bits, parity, port_number, mode)
Description The SETCOM command sets the serial communications for the serial ports.
The command will enable the Host Link protocols or define the general-pur-
pose communication.
The serial ports have 9,600 baud, 7 data bits, 2 stop bits, even parity and
XON/XOFF enabled for general-purpose communication by default. These
default settings are recovered at start-up.
Arguments • baud_rate
1200, 2400,4800, 9600,19200, 38400
• data_bits
7, 8
• stop_bits

• parity
0 = None; 1 = Odd; 2 = Even.
• port_number
See the first table below.
• mode
