Well, I came up with this this approach to get all input from the Telnet
server:
thufir@dur:~$
thufir@dur:~$ java -jar
NetBeansProjects/WeatherTelnet/dist/WeatherTelnet.jar
-----------------------------------------------------------------------------
* Welcome to THE WEATHER UNDERGROUND telnet
service! *
------------------------------------------------------------------------------
* *
* National Weather Service information provided by Alden Electronics,
Inc. *
* and updated each minute as reports come in over our data
feed. *
* *
* **Note: If you cannot get past this opening screen, you must use
a *
* different version of the "telnet" program--some of the ones for
IBM *
* compatible PC's have a bug that prevents proper
connection. *

The trick is to capture *all* input as it arrives, even without a CRLF
at the end.
