Hi,
I currently run a BBS on my BBC Micro (beebs.ddns.net for info), its running over telnet and supports vt100, ANSI and Viewdata/Teletext (on a machine that supports this i.e. a BBC Micro or Acorn Archimedes). With the machine running the BBS most of the time I don't actually get to use it so I was hoping to transition to SBBS but cannot figure out how to send the correct control codes to send viewdata to a BBC Micro client, I've tried a few different formats of files created in a teletext editor (replacing the .msg menu files) but on the BBC Micro it displays the control codes as text rather than interpreting them as teletext control codes over terminal. Is what I'm trying to achieve possible within the currenet parameters of SBBS?
Many thanks,
Fred

Thanks for the reply, your mode 7 shell sounds great. My current BBS software is OBBS from 1984 which I've modded to support sending full Mode 7 graphics frames and ANSI which it does via terminal rather than acting as a viewdata server it just uses bget to read each byte of either a teletext frame or ansi file and sends it over serial. So on a BBC you get mode 7 graphics but on an ANSI terminal you get ANSI (there's also vt100 if you have neither). It really supprises me that I can't find a BBS host which can do the same.

Videotex uses escape sequences. I can't say I've tried to use a mode 7
type file with synchronet. I wrote my own videotex script which runs on
a different port since sbbs doesn't auto detect the protocol and it's
just easier that way.

To change color and graphics, double height, separated or contiguous
etc, they're all preceded by an escape character, often referenced as
^[ it's ascii 27.

So for red text you'd put something ^[ followed by a letter A-G to
change the color to red, green, yellow, blue, magenta, cyan, or white
or @ for black.

^[] should change the background to previous foreground color

See if you can get that working to start with.

^[D^[] ^[FVIDEOTEX^[S^?^?5j^?j|^?}~j ^?55^?^?^?^?57h4k

This should provide some text and graphics. Replace ^[ with a literal
escape and ^? with a CTRL-?

If you want to download it, I've put my index page at https://www.endofthelinebbs.com/1a.vtx if you want to download it. I'm
actually going to change the format of my files but this will work. You
could try changing it to a .asc file and just accessing it from sbbs.

Good luck.

Ah, also keep in mind that you're probably trying to mix terminal and
videotex which isn't going to work. videotex is 7E1 and it sends a #
when you press return, which is actually a _ sign ASCII 96 if I
remember correctly, so that videotex page probably wont work.

In the case of terminal I would expect sending ascii 129 to change text
to red but sbbs seems to want to do something with that and sends -U
when using something like ;TYPE sysop command.

Maybe there is some way to stop sbbs of processing a file and send it
"as is". Maybe I'm talking out my ass :)

So I loaded up commstar and went into viewdata move a did ;TYPE /sbbs/text/1a.asc and it actually worked, sort of. First you'd need to
insert ^L at the top to clear the screen, and because it's all 1 line,
sbbs doesn't display it all correctly.


I've created https://www.endofthelinebbs.com/1b.asc which does display correctly when using the ;TYPE sysop command if you're in viewdata
mode, but your problem there is twofold, there's no scrolling, it only
wraps around to the top and the user still has to use ^M rather than
enter unless you re-write the shell to deal with that.

Thanks for the info, I'm not sure why but I'm unable to access endofthelinebbs.com the connection times out so am unable to see the files you have pointed to. Out of interest what editor do you use to edit your menu files that accepts ESC as an ASCII entry?

Ah, also keep in mind that you're probably trying to mix terminal and >videotex which isn't going to work. videotex is 7E1 and it sends a #
when you press return, which is actually a _ sign ASCII 96 if I
remember correctly, so that videotex page probably wont work.

My current BBS is sending the Mode 7 graphics via terminal using 8n1, obvoiusly it only displays the mode 7 graphics on a terminal that supports it (so either an acorn computer with filtering off in whichever comms software you use (e.g. commstar) or either of the PC connection options here http://beebs.ddns.net/connecting.html)...or just good old syncterm, but displays as vt100 or ANSI depending on what you select.

I was hoping there might be some BBS package out there that will just bget the file as is rather than trying to process it. Feel free to check out beebs.ddns.net to see the mode 7 graphics over terminal.

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.

YES! Thanks so much, I've made quite a bit of progress thanks to your help. In doing so has raised two more questions.
1. Do you know how to customise the prompt, the bit I've circled here: http://beebs.ddns.net/images/sync/Prompt.jpg (not sure if it's actually called prompt, as it uses characters that Mode 7 does not support. I just want to swap out the divide symbol for something else (I'm at peace with the arrows).
2. When using strings (some that are buffered with "..." like the strings used for message sender, date etc. are fine, but others will insert a chacter rather than overwrite a charater like the toggles here (http://beebs.ddns.net/images/sync/strings.png), did you find a way around this?
Thanks again, you've been a great help

1. The prompts are controlled by the menu files, probably default.src
or default.js depending on which stage of development you picked up
your sbbs.

You can use some logic like checking if the term is ANSI compatible to
give one prompt and then give something different if not.


2. You can use something like @CODE|L3@ and it'll pad to 3 characters,
if I'm understanding your question correctly. You can find more
information on padding, centering and the like on the wiki if you
search for "message variables".

Looks good so far.
