Subject: reading off socket with \n, but a specific \n.

For a while my application has used, a TCPSocket and the .each method,
to continuously receive and populate an input buffer array with messages
that were simply \n terminated.

I have now run into a situation where I need to receive a message that
happens to have \n inside of the message in a string... I can not figure
out a way to make this work.  Speed is a factor, I need this interface
as fast as possible, and in the past .each has been very fast.  Early on
I used to read 1 byte at a time until receiving \n and then would add
that to buffer, but it proved a little too slow.

Any ideas?  Thank you very much for your help.

Example of 2 traditional messages on socket, that have come in just fine
using .each on the socket...
HEAD,2,1,2\nBEAD,5,6\n

This would be two separate messages, such as:
HEAD,2,1,2
BEAD,5,6



Now I have this situation....
HEAD,2,1,2\nBEAD,5,6,"Inside:2\r\n  Outside:3\r\n  Both:4\r\n"\n

I need the two messages separately, including the inside \r and \n, like
the following:
HEAD,2,1,2
BEAD,5,6,"Inside:2\r\n  Outside:3\r\n  Both:4\r\n"



######Example code:######

 @ascii = TCPSocket.new( IP, SOCKET)

 @ascii_receive_thread = Thread.new do
   while(true)
     @ascii.each do |ascii_line|
     #Some code to put each message in an input buffer array... for use
elsewhere in program
     #I also chomp off the newline character on the end...
   end
 end
