I have an example app i found on the web which uses the following line to create a command

cmd="\x02\x06\x33\x31\x30\x33\x03";

what does it actually do? Is there  a low level language being used?

Thanks!!

it creates a string which contains the chars with those hex values: cmd[0] = 0x02, cmd[1] = 0x06, cmd[2] = 0x33 and so on (i can tell you that 0x33 is '!' 0x31 is '▼' and 0x30 is '▲' )

the basic idea is that you can use '\x' escape sequence to specify a char in a string by its hex value.

the string is just hex encoded character codes which you can look up here
http://www.lookuptables.com/

what else can you tell us about the sample code?
where is this command used?

no low level language is being used, but without some context its impossible to say what is actually happening.
