You mean a VT100 telnet client for Windows that works? I'll list a few in a second, but first I'll point out what I learned to handle field circus calls. I've found that if you take a few steps, the client that comes with 95 can be marginally usable on most Unixes-- at least, it handles emacs, nethack, and screen ok. (1) Don't resize or move the window, or access the menus, unless you don't expect to be receiving data during the operation. The temptation is great to resize to full screen during the MOTD, but if data arrives while you're fiddling with this, then the telnet client will be put in a bad state. (It looks like a ring queue gets out of sync, but I could be wrong.) (2) Upon first logging in, type 'export TERM=vt100 ; stty rows 25' or your shell's equivalent. (On some machines, notably HP/UX systems, the stty will fail. On these machines, use 'export TERM=vt100 LINES=25' instead.) (3) Resize the window to maximum size. Just grab a corner and bring it out until it don't go anymore. (On 640x480 resolutions, this may involve moving the window to the top of the screen first.) I'll occasionally think I have messed up a session, when all I had to do was scroll down. Now I just keep everything onscreen. Some other concessions may have to be made for transmitted keys, but the basic functionality is there. (Emacs users: I recommend adding (global-set-key [?\C-c ?m] 'set-mark-command) to your .emacs if your client won't send C-@. This allows C-c m to set the mark.) Now, you also wanted a usable client. I have used CRT, from Van Dyke Software (http://www.vandyke.com/). They have a very good rlogin/telnet client, including separate settings for different sessions, full VT-series emulation (with configurable color options), and-- I just plain like this, for some reason-- it can use any Windows fonts, or its internal VT100 fonts. The web site has a 30-day demo version availible, and the registration fee is light. There are more options availible, including some no-charge implementations, on Tucows (http://www.tucows.com/) and WinFiles (http://www.winfiles.com/). I am not aware of any that come with source code, although I wouldn't be suprised to see it. (I've been meaning to write a pure console-mode telnet with VT100 support, but haven't gotten around to it yet. The only similar item I saw had one minor bug in its newline handling that prevents redirection, which I need.) If you really want to go all-out, maybe you should use X. Implementations for both 95 and NT availible. There are a couple of good no-charge ones, many commercial ones (some with demos, typically 30 minute or single machine). I haven't seen any with source code. Pointers availible.
