Not strictly Linux - apologies - but a stab in the dark as so many varied folk drop by here.

I have a SupraExpress 56e PRO (Sup 2311). This great old serial modem was hooked up to my old dial-up machine some ten years ago. Since then it has been used for fax on and off.

My memory may be playing tricks, but I'm sure when I ran it on Windows with 'supervoice' it did caller id (UK spec) without any problems *I MAY BE MISTAKEN*.

I don't have the manual, and Diamond don't support these anymore so I've spent the day trying all the AT commands I can find that would normally enable/test caller ID but they all throw 'error'.

Either this unit never supported CID (I'm almost certain it did) or I have not got the right AT commands to fire it up. A selection of the commands tried via minicom are:

By any chance does anyone have a full AT command reference for this specific unit?

I've managed to get this much out of it as far as firmware et al are concerned:

Don't know if this will help you, but have a look at this site:http://www.identafone.com/modems.html

There was some info regarding British telephone systems there. Google search for "caller id supra modem" came up with some possible information.

Thanks Tom, but that just takes me back ultimately to Diamonds website and they no longer offer any support. There are driver downloads for Windows - but the full manual with the AT strings is not offered :-(

Thanks anyway - really appreciated.

Hi Dave:

if you give me an email address I can send you copies of the manual from my disk, sorry I am late..
