I am writing a server that is accessed over telnet. I need to prompt the user for information. I can send a prompt such as : "Enter your name: ", however, if the user holds backspace, it overwrites the prompt, and in general, can overwrite all the output I send the user. I dont want this to happen, obviously. Does anyone have any ideas? I thought it might be possible via sending a control character of some sort.
Microsoft telnet.exe client supports the operation:
Which will send backspace characters as deletes. This makes it so you can't backspace pretty much. This may not be entirely what you want, but being bound by a 3rd party client to interface with your server, things may be restrictive.Code:set bsasdel
If you are writing the client then you should have control of it.
If not, Many telnet programs seperate input and output into different sections. Telnet.exe is really a horrible app and many free alternatives are available.
Pitty. I wanted any generic telnet client to be able to access the server. Ahwell.
