Delete key

[Bob Rasmussen]

Here's the chain of command:

In Anzio's case, the delete key typically sends out either the Delete 
character (decimal 127) or Esc [ ~ 3, depending on the terminal type 
selected and the keys file loaded. Other clients act similarly.

The client tells the server, at login, its terminal type, which becomes 
the TERM variable.

The startup script MAY override the TERM variable. It MAY set an FPTERM 
variable.

When filePro runs, it looks at the FPTERM variable if it's defined, 
otherwise the TERM variable. Then it looks at its own termcap file to find 
the appropriate entry.

When the user hits the key, and filePro receives it, it looks through its 
termcap entry to find what key function mnemonic it matches, and acts 
accordingly.

If all works well, the Delete key is recognized as a delete key, and 
deletes the character AT the cursor (the Backspace key typically deletes 
the character to the LEFT of the cursor).

Exceptions to the above:

1) If you go through another layer, it could change things.

2) If the stty handling for the port detects the key as a signal, that 
takes precedence.

Hope that helps...
