Getting one character at a time from sockets

[penman]

Using ordinary TCP/IP sockets with the socket module in Python, I need
to get a single character at a time from the client; something
like "talk" in unix. How could I do that? (should be platform
independent if possible)

recv(1) didn't work. It waited till the carriage return came in. (non-
blocking didn't work either)

Thanks in advance.
