The current UART “Model” may be virtually changed to a less 
advanced type. In some situations it may be desirable to deactivate the 
FIFO memory, or some other options. 
The “Baudrate” may be selected in a drop-down list, or entered 
manually. If 
Manual
 is selected in the list, the value in the respective 
field is used to transmit data. NetCom checks if the configuration is 
possible, and warns otherwise. Note: The “MaxBaudrate” shown is kind 
of safe settings. It is achievable in RS232-Mode with proper cabling. 
However, the NetCom may operate in RS422 or RS485 configuration. 
These are much less sensitive for noise. It is possible to configure a 
bitrate of four times the MaxBaudrate, usually 1.843.200 bps. 
“DataBit” per character, “Parity” and “StopBit” are quite usual 
parameters. 
The FlowType is available as standard 
configuration. There is also an Advanced 
setting, which gives very specific control 
to the user.

NetCom can generate Events on RTS, 
DTR or as XON/XOFF, when the serial 
receive buffer is filled/emptied. It will 
also respect the state of CTS, DSR or 
XON/XOFF when sending data to the 
connected serial device. 
 
The “RxTriggerLevel” defines when NetCom sends the received data to 
the host. If the amount of data is this high, the data is sent. It does not 
matter if there is still data coming on the serial line. If less data is 
received, the NetCom waits some time for further data, before sending 
the buffer.

The “TxTriggerLevel” operates similar for the transmission. If the 
defined amount is received from the network, the NetCom does not 
accept more data to transmit.
