[Wylug-discuss] Terminal software

[ALLEN, David]

Hi,

I would really appreciate some help with terminal software and any answers
to my questions would be most welcome.

If you run a terminal on a client and rlogin to a server, is the terminfo
data used from the server or client? Is $TERM specified to access the
terminfo or passed thro' to the application over the rlogin. If the terminal
software is said not to support a specific terminal, why are the correct
function key escape characters displayed when the function key is pressed?
If the $TERM is set to the unsupported terminal will it work? 

Is a "colour terminal"  one in which background colour can be specified or
colours can be specified by the application, and if the application does
display in colour, how is this info passed to the terminal. If I can change
the cursor colour, for example, is colour working? Why, then, cannot the
application specify the colours?

What is the purpose of the cursors file?

As you may gather, I am very confused by this and any help would be welcome
so I can achieve a colour VT220 xterm with working function keys and graphic
characters/colours specified by my application!

Cheers

David
