There are probably other ways of doing this, but one option is to use something like
tokenize 44 $replace(%sock.read.text,<br />,$chr(44))
where %sock.read.text is the text/data read from the socket.
What I'm doing here, is replacing a multiple character string with a single character, then using the tokenize command with the ascii value of the character that I used for the replacement.
In this case, I used 44, which is the comma character.
