The EtherPoll uses 2 ports, as follows:
Port
Description
Configurable
default - 3000
EtherPoll listens at port 3000 and offers a
raw UDP connection. This port number is
configurable.
8000
Provides a telnet configuration service for
all modes.
Normal Operation Modes
In Normal Mode, the EtherPoll runs under the UDP/IP network
protocol. It will listen on a configured port number. The server
will wait for incoming data after initialization.
The EtherPoll constantly checks for data on both Ethernet and
Serial Ports.
If data from the Ethernet network is received, it will first check
for a special control symbol, filter it if found (and configured to
filter) and then send the rest of the data to the serial port.
If data from the serial port is received, it will read the data from
the serial buffer, move the data into the network buffer and
send it by ethernet when the buffer is full, when it senses an idle
timeout, or on the next tick of the transmit timer.
