Auto discovery

The auto discovery feature will discover the target name of the server connected to the serial port. This name

will be used as the alias of the serial port.

When auto discovery is active for a certain serial device, upon target connection (DCD ON event), the appliance

will send probe strings and start analyzing target device answers using regular expressions. There will be

predefined probe and match strings as well as customer-defined ones.

For each probe string sent, all regular expressions defined by the match strings will be tested. After the last cycle,

the sequence restarts. This procedure will run for a certain period (given by the auto discovery time-out

parameter) or until the target is successfully detected. If auto discovery fails, the target name will be reset to the

configured target name or to the corresponding unique default target name.

NOTE: The configured target name will be used only after the auto discovery process fails.

NOTE: The auto discovery process starts when there is variation in the DCD signal from OFF to ON (disconnect/connect the target's

cable, turn off/on the target) and when the configuration of the serial port goes from disabled to enabled and there is a target

connected in the port.

The probe strings will be used to stimulate the server (such as “\n”: a single newline).

The match strings are regular expressions where “%H” is a placeholder for the target name you want to detect,

such as:

“ \\(.*\\)(%H)\\(.*\\)” or just “xxx%Hyyy”.

The first one will extract target name from things such as:

nanana(myTarget): à results: myTarget

jhdsgjhas(tg2)kjafja à results: tg2

And the second one from things such as:

hsagdfjhagfxxxTARGETyyyyyy à resulting: TARGET
