* rewrite of the win32 dedicated console:
1) NET_Sleep() no longer watches for input, Sys_Sleep() added for waiting on input. 2) Added "CtrlHandler" for trapping Ctrl-C and other quit methods not handled by signals on windows 3) Added history support 4) Added tab completion 5) Removed automatic cursor/scroll adjustment (too problematic) 6) Enable mousewheel scrolling 7) Stop using the InputBuffer for editing This seems to work pretty well now, but I jumped the gun on a previous commit message by saying you can scroll now without locking up your server. That was only true up until the point that a server tried to print to the console, at that point it will hang until you release the scroll bar :( It may be possible to get around this by using a seperate thread for console output, but that's a whole new can of worms.

The Windows Console doesn't use signals for terminating the application

with Ctrl-C, logging off, window closing, etc. Instead it uses a special

handler routine. Fortunately, the values for Ctrl signals don't seem to
|

overlap with true signal codes that Windows provides, so calling

Sys_SigHandler() with those numbers should be safe for generating unique

shutdown messages.
