stop_bits= | stop=
This sets the number of stop bits
1 (default)
1.5
2
software_flow= | sflow=
This sets the software (xon/xoff) flow control mode.
n none (default)
r receive (xoff is transmitted when the FIFO buffer fills, xon is
transmitted when FIFO buffer is emptied)
t transmit (transmit will stop when xoff is received, and resume when
xon is received)
b both receive and transmit
xoff=
This sets the xoff character (entered as a HEX value).
0 to FF (default is 13)
xon=
This sets the xon character (entered as a HEX value).
0 to FF (default is 11)
hardware_flow= | hflow=
This sets the hardware (RTS/CTS) flow control mode, using a comma-separated
list of the following sub-options. Each sub-option is preceded by either a + or a
– to indicate if the sub-option is enabled or disabled.
±cts
When enabled, the transmission will stop when the CTS signal goes off, and will
resume when CTS goes on.
±rts
When enabled, RTS will go off when the FIFO buffer fills, and will go on again
when the receiver buffer empties.
±dsr
When enabled, the transmission will stop when the DSR signal goes off, and
will resume when DSR goes on. (Currently not supported).
±dtr
When enabled, DTR will go off when the FIFO buffer fills, and will go on again
when the FIFO buffer empties. (Currently not supported).
±rts_toggle | ±rtog
This establishes the toggle mode of the RTS signal. In this mode the RTS signal
goes on before a block of transmit characters and goes off at the end of the
block. (Currently not supported).
Example: hflow=+cts,-rts
The default for hflow is all flags disabled.
fifos=
This enables or disables the use of the FIFOs on the UART channel.
yes enabled
no disabled
The default is yes.
txload=
This sets the maximum number of bytes to load into the transmitter FIFO.
