No idea what protocol you're talking to, but in any case don't use recv 
on a TCP socket. Use either read or gets.

sfm.read(100) will wait until exactly 100 bytes has been read, or the 
other end has closed the connection.

sfm.gets will wait until a newline has been read, or the other end has 
closed the connection.

What exactly you should do depends on the protocol - in particular, how 
it marks the end of a reply. Given that the request is terminated by a 
newline, it would make sense for the reply to be terminated by newline 
too.
