COM Port Remote Settings Properties
The parameters on this tab control the operation of the serial port on the NetCom
+
Device. They
are defined and activated by the driver software.
Tx Trigger Level
: The serial port on the NetCom
+
Device buffers data for transmission to external
devices. If the amount of data in this buffer drops below this level, the NetCom
+
is
capable to receive new data. It will send a related event to the driver software.
Rx Trigger Level
: When the serial port has received this amount of data, these are sent to the
driver on the connected computer. If the amount is less than this, the NetCom
+
applies
a timeout of about 5 character times. This means the timeout varies with the serial
transmission speed.
The
Remote Flow Control
panel signals the NetCom
+
to perform the handshake on its own. This
is necessary, because the network delay of some milliseconds is to long for reliable operation in
many situations.
