IP Bridge V3/V3+
Software command description
The commands can be sent via three possible links (TCP, UDP, RS-232). If you are
using TCP and/or UDP link, you have to connect via the port 1024 to communicate with
the serial port #1 and 1025 for the serial port #2.
All commands follow this syntax:
Chr(254) + Chr(248) + Chr(8) + Chr(2) + COMMAND + Chr(3) + Chr(3)
Commands listing:
Request ECHO:
Sequence: Chr(254) + Chr(248) + Chr(8) + Chr(2) + Chr(4) + Chr(3)
At reception of this sequence the bridge returns this sequence in Echo.
* This sequence is not redirect to the serial port
* Very useful to know if the bridge is active (Watch Dog)
