Tx Network Buffer Size
: If the application sends small chunks of data to the driver, these are
buffered to send them in one large packet. This parameter defines the size of the buffer.
And also the maximum packet size sent to the serial port by the driver software.
Rx Network Buffer Size
: This is the size of the buffer to receive data from the NetCom
+
.
Automatic Trigger
: based on internal rules, this checkbox selects a best practice value for
Tx
Trigger Level
. Deactivate it to control that parameter manually.
Tx Trigger Level
: Controls the time when data is sent to the NetCom
+

driver may use a timeout to determine when to send them.
