If it can be done, you need to send the string which corresponds to the `civis' terminfo entry (`vi' termcap entry). and make my programs accept characters typed into a terminal without you having to press enter first? Put the terminal into raw mode using tcsetattr(). -- Glynn Clements [EMAIL PROTECTED]

Whenever a key is pressed, you need to send the corresponding ASCII code via the serial connection. 1. How do I describe this terminal in termcap/terminfo? You only need a termcap/terminfo entry if you wish to use the terminal for `full-screen' applications, e.g. vi, Emacs. With only 2 lines, this isn't likely to be of much use. I have just read something about the curses library, however a book on the curses library is not available here in India. Where could I get more info/downloadable tutorial perhaps? I'm currently reading the man page. The manual pages should provide adequate documentation. Try looking at some existing entries (use `infocmp' to read terminfo files). 2. How do I make sure that Linux initialises this terminal on startup? 3. How do I make sure that the getty login processes are carried out on starting? If the terminal will be permanently connected, add a getty process to /etc/inittab, e.g. s1:12345:respawn:/sbin/agetty 19200 ttyS0 dumb `19200' is the line speed, `ttyS0' is the serial port, and `dumb' is the terminal type (used to initialise $TERM). -- Glynn Clements [EMAIL PROTECTED]
