In SBBS set your terminal accordingly

[+] Use automatic terminal type detection? No
[+] Does your terminal support UTF-8? No
[+] Does your terminal support ANSI? No
[+] Are you using a CBM/PETSCII terminal? No
[+] Does your terminal support IBM extended ASCII (CP437)? Yes
[+] HIT your BACKSPACE or DELETE-LEFT key: Character 127 (7Fh)
received.  

Then create a file like this:

<81>RED
<82>Green
<83>Yellow
<86><88>Flashy!
<84><9d><83>My favorite yellow on blue

You'll need to replace <81> and <82> with the comparable ascii code. In
vi you can do ^V129 or if you want to enter the hex value ^Vx81

Before saving, make sure your file is iso-8859-1 format with

:set fileencoding=iso-8859-1

All this assumes you're on Linux using vim. If not then No idea how
you'd do it in windows. I guess you can use notepad and use the ALT 129
method for entering control codes.

Anyway, I did all that and put my file.asc in the menu directory and
just tried it with bbs.menu and it printed fine.

Hope that helps.

You'll find all the codes in a chart at the back of the BBC Micro User
Guide, something like page 476.
