Subject [jira] Created: (NET-180) Telnet EOR is "consumed" by TelnetInputStream when in BINARY transmission

Telnet EOR is "consumed" by TelnetInputStream when in BINARY transmission
-------------------------------------------------------------------------

                 Key: NET-180
                 URL: https://issues.apache.org/jira/browse/NET-180
             Project: Commons Net
          Issue Type: Bug
    Affects Versions: 1.4
         Environment: Applies to all platforms
            Reporter: Chris Jones


I have a TN5250 client (see rfc1205) which extends TelnetClient. Basically, the client negotiates
BINARY transmission and operates in block-mode. However the host sends IAC EOR at the end
of each block in order to notify the client that the transmission of the block of data is
complete, and the client should build the display. The problem is that the IAC EOR is "consumed"
by the TelnetInputStream and therefore never reaches the client.

There are a few ways this could be handled, here are couple of suggestions (the 2nd is probably
better):-

1. Within TelnetInputStream, treat IAC EOR as data when in BINARY transmission state
2. Extend TelnetNotificationHandler and send notifications of all Telnet Commands received
