This article provides steps to disable Windows Telnet character duplication.
Users can connect to other machines, such as PuTTY, TeraTerm, ZOC and Windows CMD Telnet using AllegroSurf's Telnet Proxy Server feature. AllegroSurf's Telnet Proxy Server is configured to echo or duplicate characters back to the client. This process was developed as an improvement to the original Telnet servers which did not provide visuals for users to know if a typographical error has been made. Telnet clients echoed characters locally to cut down on traffic and increase accuracy. The results are duplicate characters when both the client and the server echo characters.
This duplication process ends as soon as a connection is opened to a remote server through AllegroSurf, at which point, it is passing data back and forth between the destination server and the client.
