SB (Stop Bits)
Sets or displays the number of stop bits for UART communications.
Parameter range
0 - 1
Parameter
Configuration
0
One stop bit
1
Two stop bits

RO (Packetization Timeout)
Set or read the number of character times of inter-character silence required before transmission
begins when operating in Transparent mode.
RF transmission also starts after 100 bytes (maximum packet size) are received in the
DI
buffer.
Set
RO
to
0
to transmit characters as they arrive instead of buffering them into one RF packet.
Parameter range
0 - 0xFF (x character times)
Default
3
TD (Text Delimiter)
The ASCII character used as a text delimiter for Transparent mode. When you select a character,
information received over the serial port in Transparent mode is not transmitted until that character
is received. To use a carriage return, set to
0xD
. Set to zero to disable text delimiter checking.
Parameter range
0 - 0xFF
Default
0x0
FT (Flow Control Threshold)
Set or display the flow control threshold.
The device de-asserts CTS when
FT
bytes are in the UART receive buffer.
