Looks like I'm writing a uMite compatible VT100 emulator from scratch.

I'd rather not replicate VT100 controls I don't need.

Is it possible to obtain a list of the controls used by EDIT on the uMite?

Thanks

Hi there Jeff.

Are you aware of the fact that Geoff is about to release a VT100 compatible terminal program?
I'm not sure if it is written in MMBasic for the uM, but it was talked about as a thing that was being developed, so that it could be used to program the uM, and work as a general purpose VT100 terminal for other purposes too.

It may well do everything you want, and you may then NOT need to write your own one...Edited by Grogster 2014-05-18

I'm writing it for the Propeller uController...

I've got everything working tonight except function keys.
Not sure what the uMite is expecting for them. Googling VT100 commands tonight.

The VT100 control codes I implemented in MMEdit are
CR
LF
BS
esc D
esc M
esc [H
esc [f
esc [J
esc [A
esc [B
esc [K
esc [m

For the keyboard routines I did this:

[VTkeyPress]
VTk$=Inkey$
'print len(VTk$),asc(VTk$), asc(right$(VTk$,1))
if len(VTk$)>1 then
VTcmd=asc(right$(VTk$,1))
select case VTcmd
case 13
VTk$=""
case 27
VTk$=chr$(27)
case 37 'left arrow
VTk$=chr$(130)
case 38 'up
VTk$=chr$(128)
case 39 ' right
VTk$=chr$(131)
case 40 ' down
VTk$=chr$(129)
case 45 ' insert
VTk$=chr$(132)
VTins=1
case 46 ' delete
VTk$=chr$(127)
case 36 ' home
VTk$=chr$(134)
case 35 ' end
VTk$=chr$(135)
case 33 ' page up
VTk$=chr$(136)
case 34 ' page down
VTk$=chr$(137)
case 18 ' alt
VTk$=chr$(139)
case 112 'F1
VTk$=chr$(145)
case 112 'F1
VTk$=chr$(145)
case 113 'F2
VTk$=chr$(146)
case 114 'F3
VTk$=chr$(147)
case 115 'F4
VTk$=chr$(148)
case 116 'F5
VTk$=chr$(149)
case 117 'F6
VTk$=chr$(150)
case 118 'F7
VTk$=chr$(151)
case 119 'F8
VTk$=chr$(152)
case 120 'F9
VTk$=chr$(153)
case 121 'F10
VTk$=chr$(154)
case 122 'F11
VTk$=chr$(155)
case 123 'F12
VTk$=chr$(156)

case else
'print len(VTk$),asc(VTk$), VTcmd
VTk$=""
end select
end if
re=MMsend(VTk$)
wait

The code is in Liberty Basic but should be clear enough. I have changed things a bit for MMEdit2 but this is the easiest to decipher.

Extracting keyboard presses from a multitasking operating system can be a real pain.

The code has grown along with MM Basic, adding new VT100 control codes as they are added to the Maximite. The MicroMite may not implement all these codes.

@Jim,

That will help me greatly! I'll digest that message in the morning.
I hooked putty to my test rig and found working codes to get my Fkeys and cursor keys working, but I had not implemented them all.

@All

Here's a link to the project as it progresses.
http://propellerpowered.com/forum/index.php?topic=574.0

The setup is a Propeller uController hooked to a VGA monitor, keyboard, and SD card with serial communication opened to the uMite console. I know Maximite exists, and perhaps this is a little replication of that project, but there are some very interesting sprite/graphics and SID-type audio objects which run on the Propeller that I'd like to chain to the BASIC on the uMite. It's ability to create FUNCTIONS and SUBS which can be called from anywhere should make this project interesting.
