> Hi,
> We are using your library to connect/login to some Windows and Foundary devices via Telnet.
> The source(client) is a Windows 7 professional windows machine and all the servers we
are trying to connect are Windows machines running Microsoft(R) Windows(R) Server 2003, Standard
> In version 2.2 we were able to connect and then login successfully to these devices with
no issues.
> However, on upgrade to 3.3 version, we are unable to login to these devices successfully.
> In v 3.3, after entering the username and hitting enter, there is no response at all.
However in v 2.2, as soon as you enter the username and hit enter, password prompt comes back
for us to enter the password and we are logged in successfully. 
> I compraed the packet captures between the two versions for the same target server machine.
The only difference I can see is when the user name is set, in v2.2 a '\r' is appended to
the end of the username where is v 3.3, this '\r' is missing. Is this due to any change in
> I can provide the packet capture/logs if required. Please let us know if this is a known
issue or if there are any workarounds. 
> Thanks
