Integration with Satel alarm system via ETHM-1

Correction: default receive pattern is '*l' - a single line, not the whole result. Receive() will return partial result as a third return value when an error occurs (that's why you are getting an empty string). So you can use '*a' pattern to receive everything until timeout occurs. This is not the most efficient way, but it will work

Code:

data, err, partial = client:receive('*a')

-- error
if not data then
  data = partial
end

-- do something with data that's available
if data then
  parsedata(data)
end

client:close()

As for hex logging, new firmware will have loghex() function to make this easier.
