Utilities - Comms Terminal
Comms Terminal can be used view characters that are received by the local PC COM port or by any RTU
port in the telemetry system. Comms Terminal can also be used to send AT commands to devices that
support the AT command set.
Comms Terminal can be used with a local PSTN modem or GSM (connected to the PC) to dial into a remote
RTU for diagnostics and configuration.
Ethernet messages between RTUs can be viewed using the Wireshark program and a PC that is connected
to the same Ethernet network. To download a free copy of Wireshark, visit www.wireshark.org. A Kingfisher
version of Wireshark is also available from www.cse-semaphore.com/mykingfisher that has support for
deciphering the Kingfisher protocol.
Comms Terminal can be used for the
Local PC Port
(which uses the COM port setting in Configuration,
PC Setup), or for a Remote RTU Port. To access a
remote RTU port, a valid RTU Address (1-249) and
Port Number (1-16) must be entered.
Echo Characters can also be selected, which will
echo any send characters back to the display
window.
Once the port has been specified, a terminal window is then opened. ASCII characters can be sent to the
specified port (CPU or MC ports) and characters received can be viewed (for CPU only). Characters
received on MC ports cannot be viewed.
Comms Terminal is very useful for communicating with dial option boards or local PSTN modems. Some
Hayes AT modem commands and responses are shown below.

Connection information. After the CONNECT 9600 statement appears, Toolbox
can be used to view the RTU status, download a configuration or perform any
other function that would be possible if Toolbox were directly connected to the
remote RTU with a cable. If Toolbox is used to interrogate the RTU before this
