Could someone tell me if the following command is correct, can you use a socket.match command or is this command only usable with the serial port ?

label = socket.match("get //counting/254/56/13 level \r","\r",1250);

I want to request a level of a device and display in one. Or do i need a separate

socket.write and then a socket.read ?

Also could some point me in the direction or tips on stripping of relevant data from the response, the command above should i think read the response up to the carriage return. But if i wanted to extract data between the word level= and the carriage return is this possible.

Sorry if it doesn't make sense i am rather new to this script stuff.

The response to the "Get level" command above will be something like "//house/254/56/13: level=153"

A lot depends on the device you are dealing with. In general if the device only sends out data in response to a command/query, then you must first do the write and then do a read to get the response data

If the device is periodically sending out data through its serial port in an unsolicited manner, then you do not need a write, but must do reads. That, unsolicited serial input, also brings up whole issues that are two complex to address here so avoid it if you can.

Sockets don't do matches, only serial ports do matches. Please review Appendix A of the dev guide closely!

For parsing responses, read up on Regular Expressions and capture groups.

If you are Level 1 certified, download one of the denon RS232 scripts from philips. They use Regular Expressions and should help to get you started.
