Does anybody have any suggestions for a component to display status or
terminal text that will allow limited enhancement (colour, possibly
underline etc.)?
Over the last few weeks I've been tinkering with an emulator for an
obsolete mechanical terminal (IBM 2741), including support for the APL
character set. I started off using a listbox for simple output, noting
that this didn't have provision for multiple colours or marking the
insertion point. I moved on to stuffing characters into a memo, this
allowed me to force a current-position marker but still had no colour.
Looking at the CmdLine component, it appears OK as a command window
(i.e. accepting keyboard input etc.) but isn't so hot when the principal
requirement is to display text pushed into the underlying strings
storage from elsewhere: in particular, there isn't a way to force the
insertion point marker to the end of what's just been output.
I'm sure I'm not the only person who wants to do this sort of thing:
does anybody have any recommendations?
Mark,
I don't have any recommendations but I'm following this message thread
with much interest. Last fall I wrote a "serial debug terminal" with
Free Pascal and fpGUI and that program has proved to be one of the most
useful simple programs I've written in a long time. I've customized it
a few times already for real work projects and I also have some other
projects planned. If you want to see how simple the present code is see
the "DbgTerm.pas" program at this page:

Right now you can't put the cursor in the terminal and send characters
by typing them, but rather there are separate SendEdit and SendButton
components. I'd like to implement a more standard "terminal" operation
so what you are discussing here applies to that.
I'd like to keep the present DbgTerm as a very simple example of serial
communications code but I will consider having a more complex terminal
program too. I've run into many people who need a replacement for
HyperTerminal since it has been gone from Vista and later Windows editions.
