From: root@nccnat.UUCP (Paul Shields) Newsgroups: comp.sources.misc Subject: v02i100: GNU Termcap ported to MS-DOS. Message-ID: <8804202315.0.UUL1.2#235@nccnat.UUCP> Date: 21 Apr 88 04:15:16 GMT Approved: allbery@ncoast.UUCP comp.sources.misc: Volume 2, Issue 100 Submitted-By: "Paul Shields" <root@nccnat.UUCP> Archive-Name: ms-termcap Here is GNU Termcap, from GNU Emacs, ported to MS-DOS. I find this quite useful with an ansi screen driver, and have managed to get Micro Emacs to work over the RS232 port this way. Sorry about the fact that there's no documentation. Please refer to the termcap library documentation for Unix. One last note: please examine config.h for possible changes.
