[net] ETX in Telnet stream and available() method

Hi all,
I'm trying to perform a telnet bridge with my Java code.

First I connect to SERVER1 via telnet, then from its terminal I connect to SERVER2 via telnet.

When I want to exit the telnet connection on SERVER2 (the only way is EXIT;) I get the stream as reported below.

The ETX character causes the InputStream.available() method read until the < prompt and I can't get the prompt of SERVER1 again.
Does this ETX causes a break in the stream? How can I read until the > prompt?

Thank you
Gennaro


C:\>telnet SERVER1 23
