A note on modem codes
The firmware labelled 'BT' is the recommended mode code for UK lines.

Other modems codes are available, some are newer and others older than the 'BT' 576D17 modem code. The digits indicate the version number, with a higher number being a later revision. Each digit is HEX so 'F' is the highest digit.
