Hi Folks,
I've checked in my patch for menu & command list editing on dumb
terminals.
CF: Subject: Making MENU on dumb terminals work
Date: Sat, 27 Jan 2001 09:57:38 -0800
We have tested it on console, VT terminals, dumb terminals and I
consider it stable (if there are problems, nobody knows ;-), let me
know).
For all who don't know what this is for:
* Serial support is used for embedded/server machines without graphic
cards where the console is connected to a serial cable to a
terminal or terminal program on another computer.
e.g. (connect COM1 = /dev/ttya with a serial line to a terminal)
serial --unit=0
terminal --timeout=0 serial
(see `help serial' resp. `help terminal')
* The default for serial assumes VT100 capabilities of the connected
terminal for position queries and cursor positioning.
* Where VT100 capability can't be assumed (batch processing, emacs
comint buffers, poor terminal emulations), the dumb terminal can be
configured and NOW still use menu and command list selection and
editing.
terminal --dumb ...
Some ideas for future directions:
* terminal --query ...
Check out terminal capabilities (see `qterm' for an example).
* GRUB shell: --batch
Output of --batch is ugly, maybe the terminal dumb setting could be
used for --batch to make it more natural.
* Fast selection of menu entries with keys (numbers as shortcuts?) - I
remember discussions on the list about that already, it didn't make
it to the mainstream, however.
* On line buffered terminals (e.g. emacs comint) it is rather tricky
to operated the menu (typing a key followed by RET always may have a
side effect, since GRUB interprets the KEY and the following RET).
* On really dumb terminals (e.g. emacs comint) not even ^H = BACKSPACE
is supported, making the output rather ugly.
