NOTE:
You can use the CTS output from an entraNET radio for Data
Carrier Detect (DCD) sense. It is always asserted (high) when
flow control is set to
NONE
.
CTS_CTRL:
The radio asserts this line as long as it can accept
data on the serial port. When the radio’s internal serial buffers
are full and it can’t accept any more data on the port, it
de-asserts (low) the CTS line.
CTS_RTS:
CTS follows RTS logic. When RTS is asserted by
the DTE/PC and the internal serial buffers are not full, the
radio asserts CTS as well. When RTS is de-asserted, CTS is
de-asserted as well.
RTS_CTS:
In this case, RTS and CTS behave independently.
RTS is asserted by the DTE/PC as long as it can accept radio
data. When its buffers are full, the DTE/PC de-asserts its RTS
line. The radio detects this change and stops transmitting data.
The CTS line in this mode behaves the same as in CTS_CTRL
mode.
FORMAT=<format>
—Sets or displays the
COM2
port data characters,
parity, and stop bits setting. Valid data parameters are:
7N1
—seven char bits, no parity, one stop bit
7N2
—seven char bits, no parity, two stop bits
7O1
—seven char bits, odd parity, one stop bit
7O2
— seven char bits, odd parity, two stop bits
7E1
—seven char bits, even parity, one stop bit
7E2
—seven char bits, even parity, two stop bits
8N1
—eight char bits, no parity, one stop bit (default setting)
8N2
—eight char bits, no parity, two stop bits
8O1
—eight char bits, odd parity, one stop bit
8O1
—eight char bits, odd parity, two stop bits
8E1
—eight char bits, even parity, one stop bit
8E2
—eight char bits, even parity, two stop bits
NOTE:
Entering data formats other than those listed above may cause
undesired operation.
GROUP=<ID>
— Sets or displays the Group ID that this transceiver
belongs to at the AP, for purposes of serial data multicasting (0-15).
INTERGAP
— Sets or displays the transceiver inter-packet gap status.
Optional arguments:
IO
—For incoming or outgoing serial data.
IN
—For incoming serial data only.
IOL
—For incoming or outgoing (low latency) serial data.
INL
—For incoming (low latency) serial data only.
