Attached are some escape codes I have extracted from various posts for use on a VT100 screen.
I was running some of these to try and understand them
I was using MMedit and quite a few worked ok but all of the lines borders etc would not work.Then none of them worked and I cannot understand what has happened.
I tried them on Teraterm and some of them worked as they did on on MMedit.
I put the latest software into the micromite and ran the same programme on another computer also using MMedit same result.
I am not using a VT100 screen but using the computer screen.
These codes are most confusing . There must be some guides on Syntax somewhere.
Your help would be greatly appreciated
Jeff

MMEdit only uses a subset of the VT100 controls.
It is intended for basic use only.

You may get better success from TeraTerm or Putty.

Thanks Jim sorry for delayed reply
Yr mmedit is the bees knees I really like it.
As regards the escape codes . the only ones I really wanted was to position the cursor and clear the screen.
What I find odd is that if I programme using mmedit then switch to teraterm they work ok.
For the benefit of others with this problem I found that if I select "VT" in the chat window they work ok . Maybe that is what I should have been doing all along
regards Jeff

That's it.

The VT button puts it into VT-100 mode.
the A is ASCII mode which does not recognise the esc codes, but is good to se what's being spat out.

The other code I use a lot is clear to end of line;

It helps tidy thing up if the buffer over runs.

Phil.
