The use of these custom character sets was generally incompatible between manufacturers. Unless a caller was using terminal emulation software written for, and running on, the same type of system as the BBS, the session would simply fall back to simple ASCII output. For example, a Commodore 64 user calling an Atari BBS would use ASCII rather than the native character set of either. As time progressed, most terminal programs began using the ANSI standard, but could use their native character set if it was available. In the UK, the BBC Micro based OBBS software, available from Pace for use with their modems, optionally allowed for color and graphics using the Teletext based graphics mode available on that platform. Other systems used the Viewdata protocols made popular in the UK by British Telecom's Prestel service, and the on-line magazine Micronet 800 whom were busy giving away modems with their subscriptions   .
