I'm trying to figure out why exactly Putty sends a signal on connection, i pasted it below, but its really just boxes:

Code (text):

 
input> "���� ����'������"

Either way, i need to be able to run some type of pre evaluation of the input, I'm new to Ruby
so any help would be great! So far i've been playing with a regexp:

Code (text):

 
unless data =~ /abcdefghijklmnopqrstuvwxyz1234567890/i

But I'm sure there's a better way. :wink:

	I believe it sends out some telnet negotiations. Try to print the characters as decimal values to make more sense of it.

	I don't really understand what you mean. Do you want to filter out all non-alpha numeric?

	Hey, what exactly you want to do with that data is important in determining how to handle it. What is the goal?

I realized after reading up on the Telnet support that they are in fact telnet options as Scandom said. I was able to develop a quick routine to handle it, but I still havent figured out how to handle byte-by-byte support for Win32 telnet systems. Does anyone have a good example of how one might go about this?

Come on man, what about all those Win95 users out there!!! Just call me paranoid, but if you go down that road, what terminal dosn't support ANSI color ETC.

Mine is amber though, and currently doesn't work :(

	It's no surprise that MUDs as a genre haven't evolved much if that's the target client architecture...

	Especially if you consider that the VT220 has more advanced terminal handling than the average mud client.

The challenge of moving mud server developers out of the 1960's teletypes and into the 1970's virtual terminals is apparently insurmountable. ;-)
