Detection of subsequent data by poll()

Quoth rupe at metro.yak.net (Rupert Scammell):
| I recently wrote a program that uses the select.poll() method in order
| to
| check for incoming data on multiple listening sockets.  When I open a
| connection to one of the listening sockets (e.g. via telnet), the
| program accepts the first item of data sent (a character string with a
| trailing CRLF).  However, subsequent calls to poll() never appear to
| detect more strings sent in the same connection to this socket.  The
| file descriptors for the sockets are all correctly registered with the
| poll object.
|
| Is there a way to make poll() detect this incoming data without having
| to close and re-open a connection to the socket in question each time?
|
| Any suggestions would be appreciated!

Suggestion:  post a program that shows the problem.  Also suggest
you mention your platform.
