Telnet client: Support Listener Notification of Incoming Data
-------------------------------------------------------------
Key: NET-344
URL: https://issues.apache.org/jira/browse/NET-344
Project: Commons Net
Issue Type: New Feature
Components: Telnet
Affects Versions: 2.0
Reporter: Archie Cobbs
I am in the process of trying to implement a Java client for [RFC
2217|http://tools.ietf.org/html/rfc2217], which is the protocol for accessing
serial ports over TCP. Unfortunately, the commons-net telnet client is
insufficient for this relatively simple task.
There are two missing features in the commons-net telnet client code, one of
which is a show stopper (NET-343) and the other of which would be a "real nice
to have". This issue documents the second problem:
The API I am trying to support requires the ability to notify a listener that
new incoming data is available. This would be trivial for me to do if only my
library could somehow itself get a listener notification from the
{{TelnetInputStream}} reader thread every time it reads new data.
Unfortunately, there's no API provided for doing this, even though it would be
trivial. So I have to implement a hack that requires a wrapper {{InputStream}}
with yet another internal reader thread, etc. Bleh.
I'm going to attempt to come up with a patch and will attach it here if
successful.
