I use a socket connection in a subroutine that closes after I send a command. The easiest way that I have found to read the text back is using the `shutdown ($socket_name, 1)`. You can then run a `while(<$socket_name>){ print $_; }` [download] to return whatever the prompt/responce is. Again, for each command that I send, I create a new socket connection send the command and disconnect/kill the socket. Also once the while loop is in place, you can use a regex to take what you want out, like the prompt, since it is making a new connection everytime.	[reply] [d/l] [select]

Ok ask your self this, what is a line? if you can answer it without using '\n' then you can read a line without sending '\n'. If i were you i would seriously consider limiting the length of a line to 80 characters, that way when you just read 80 chars you consider it a line or just stick to what works and send '\n'.	[reply]

The hardest part about sockets is knowing when to stop reading. You can invent a line-oriented protocol, or use some other indication (like a byte count followed by that many bytes). Knowing what to use is an art call, decided by experience and study of the prior art. Good luck in your quest!	[reply]
