FT (Flow Control Threshold)
Sets or displays the flow control threshold.
De-assert CTS when the number of bytes specified by the FT parameter are in the DIN buffer. Re-
assert CTS when less than FT - 16 bytes are in the UART receive buffer.
Binary command
0x24 (36 decimal)
Parameter range
DI buffer size minus 0x11 bytes
Default
0xBBF - DI buffer size minus 0x11 (17 decimal)
NB (Parity)
Set or read the parity settings for UART communications.
Parameter range
0 - 4 (S3* hardware)
0 - 5 (S3B hardware)
* The S3 hardware variant is a legacy design that is obsolete. New and old designs should use the
S3B hardware variant.
Parameter Configuration
0
8-bit (no parity )
1 8-bit even
2 8-bit odd
3 8-bit mark
4 8-bit space
5 9-bit data (S3B Hardware)
Default
0
Bytes returned

PK (Maximum RF Packet Size)
Sets or displays the maximum size of RF packets that a device in Transparent operating mode (AP = 0)
transmits. You can use the maximum packet size along with the RB and RO parameters to implicitly
set the channel dwell time.
