Tx FIFO Trigger
Tx FIFO sizes from 1 to 16 bytes are available, and the default value is 16 bytes.
RTS/CTS Hardware Flow Control
This feature is for more flexible driver behavior. If set to “Disable” (default), CTS
signal is not needed for tty port to transfer data and RTS/CTS hardware flow control
function in driver is disabled. On the contrary, if set to “Enable”, CTS signal is
needed for tty port to transfer data and RTS/CTS hardware flow control function in
driver is enabled.
Port Monitoring
This utility gives you a quick view about all the MOXA ports' activities. You can
easily learn each port's total received/transmitted (Rx/Tx) character count since the
time when the monitoring is started. Rx/Tx throughputs per second are also reported
in interval basis (e.g. the last 5 seconds) and in average basis (since the time the
monitoring is started). You can reset all ports' count by <HOME> key. <+> <->
(plus/minus) keys to change the displaying time interval.
Press Enter on the port, that cursor stay, to view the port's communication
parameters, signal status, and input/output queue.
