The telnet protocol is supposed to be able to pass term type (TELOPT_TTYPE == 24). I agree that some telnet programs are quite stupid about this. However it's not too hard to find a client that works sanely in this regard. > How does the server know what terminal type the remote client is > emulating? see above.

It is distributed with a terminfo database, can read from this database in a user defined directory (if you lack root access to just install it), and takes arguments to newterm to define which term type to use: SCREEN *newterm(char *type, FILE *outfd, FILE *infd); .....The routine newterm() should be called once for each terminal. It returns a variable of type SCREEN * which should be saved as a reference to that terminal. The arguments are the type of the terminal to be used in place of $TERM, a file pointer for output to the terminal, and another file pointer for input from the termi- nal (if type is NULL, $TERM will be used). The program must also call endwin() for each terminal being used before exit- ing from curses. If newterm() is called more than once for the same terminal, the first terminal referred to must be the last one for which endwin() is called. > That given, curses works very nicely. Yeah, the only real problem is a client telnet that does not support negotiation of term type (which it is SUPPOSED to). -Kat </PRE> <!--X-Body-of-Message-End--> <!--X-MsgBody-End--> <!--X-Follow-Ups--> <HR> <ul compact><li><strong>Follow-Ups</strong>: <ul> <li><strong><A NAME="00756" HREF="msg00756.html">Re: [MUD-Dev] Clients</A></strong> <ul compact><li><em>From:</em> J C Lawrence <claw#under,engr.sgi.com></li></ul> <li><strong><A NAME="00621" HREF="msg00621.html">Re: [MUD-Dev] Clients</A></strong> <ul compact><li><em>From:</em> Travis Casey <efindel#polaris,net></li></ul> </UL></LI></UL> <!--X-Follow-Ups-End--> <!--X-References--> <UL><LI><STRONG>References</STRONG>: <UL> <LI><STRONG><A NAME="00556" HREF="msg00556.html">Re: [MUD-Dev] Clients</A></STRONG> <UL><LI><EM>From:</EM> coder#ibm,net</LI></UL></LI> </UL></LI></UL> <!--X-References-End--> <!--X-BotPNI--> <UL> <LI>Prev by Date: <STRONG><A HREF="msg00570.html">Re: [MUD-Dev] Net protocols for MUDing (was: Moore's Law sucks)</A></STRONG> </LI> <LI>Next by Date: <STRONG><A HREF="msg00572.html">Re: [MUD-Dev] The MLI Project</A></STRONG> </LI> <LI>Prev by thread: <STRONG><A HREF="msg00556.html">Re: [MUD-Dev] Clients</A></STRONG> </LI> <LI>Next by thread: <STRONG><A HREF="msg00621.html">Re: [MUD-Dev] Clients</A></STRONG> </LI> <LI>Index(es): <UL> <LI><A HREF="index.html#00571"><STRONG>Date</STRONG></A></LI> <LI><A HREF="thread.html#00571"><STRONG>Thread</STRONG></A></LI> </UL> </LI> </UL> <!--X-BotPNI-End--> <!--X-User-Footer--> <!--X-User-Footer-End--> <ul><li>Thread context: <BLOCKQUOTE><UL> <LI><STRONG>Re: [MUD-Dev] Clients</STRONG>, <EM>(continued)</EM> <ul compact> <ul compact> <ul compact> <LI><strong><A NAME="00521" HREF="msg00521.html">Re: [MUD-Dev] Clients</A></strong>, Katrina McClelan <a href="mailto:kitkat#directcheck,aries.net">kitkat#directcheck,aries.net</a>, Wed 18 Feb 1998, 05:29 GMT <UL> <LI><strong><A NAME="00529" HREF="msg00529.html">Re: [MUD-Dev] Clients</A></strong>, Nathan F Yospe <a href="mailto:yospe#hawaii,edu">yospe#hawaii,edu</a>, Thu 19 Feb 1998, 01:28 GMT <UL> <LI><strong><A NAME="00675" HREF="msg00675.html">VEIL (was: Re: [MUD-Dev] Clients)</A></strong>, Brandon Gillespie <a href="mailto:brandon#roguetrader,com">brandon#roguetrader,com</a>, Tue 03 Mar 1998, 12:26 GMT </LI> </UL> </LI> <LI><strong><A NAME="00556" HREF="msg00556.html">Re: [MUD-Dev] Clients</A></strong>, coder <a href="mailto:coder#ibm,net">coder#ibm,net</a>, Mon 23 Feb 1998, 00:59 GMT <UL> <LI><strong><A NAME="00571" HREF="msg00571.html">Re: [MUD-Dev] Clients</A></strong>, Katrina McClelan <a href="mailto:kitkat#directcheck,aries.net">kitkat#directcheck,aries.net</a>, Tue 24 Feb 1998, 04:44 GMT <UL> <LI><strong><A NAME="00621" HREF="msg00621.html">Re: [MUD-Dev] Clients</A></strong>, Travis Casey <a href="mailto:efindel#polaris,net">efindel#polaris,net</a>, Fri 27 Feb 1998, 12:22 GMT </LI> <LI><strong><A NAME="00756" HREF="msg00756.html">Re: [MUD-Dev] Clients</A></strong>, J C Lawrence <a href="mailto:claw#under,engr.sgi.com">claw#under,engr.sgi.com</a>, Thu 19 Mar 1998, 00:08 GMT </LI> </UL> </LI> </UL> </LI> </UL> </LI> </ul> <LI><strong><A NAME="00549" HREF="msg00549.html">Re: [MUD-Dev] Clients</A></strong>, Greg Munt <a href="mailto:greg#uni-corn,demon.co.uk">greg#uni-corn,demon.co.uk</a>, Sat 21 Feb 1998, 11:47 GMT <UL> <LI><strong><A NAME="00550" HREF="msg00550.html">Re: [MUD-Dev] Clients</A></strong>, Matt Chatterley <a href="mailto:matt#mpc,dyn.ml.org">matt#mpc,dyn.ml.org</a>, Sat 21 Feb 1998, 13:30 GMT </LI> </UL> </LI> </ul> </ul> </LI> </UL></BLOCKQUOTE> </ul> <hr> <center> [ <a href="../">Other Periods</a> | <a href="../../">Other mailing lists</a> | <a href="/search.php3">Search</a> ] </center> <hr> </body> </html>
