Be _very_ careful as the "termcap.src" file from that source is full of bugs.

There are 1599 terminal entries in the file, but there are:

18	unparsable parameterized strings that are in conflict with the 
	termcap documentation

234	NULL chars at a place where the termcap documentation requires '\200'

135	bad quotes that are not understood by an appliction that
	follows the termcap documentation

43	stray entries that make no sense at all

This is a total number of 387 fatal errors or 240 bad entries per 1000 

To compare: /etc/termcap from Solaris has 433 terminal entries but there are 
only 16 defective entries. This is an error rate of 37 bad entries per 1000 

To verify my statements:

-	get recent schily tools ftp://ftp.berlios.de/pub/schily/

-	compile

-	run the program "termcap" (a termcap compiler) with:

	termcap if=filename > newcap

filename is the name of a file to parse and to compile
newcap is the output file that contains comments with
hints to repaired bugs and to unrepairable bugs.
