The following information is provided as is, and the authors take no responsibility for the correctness.
The SCS data stream has fifty-six control codes. The IBM 3287 printer supports 18 of the SCS control codes, and HP printers support 17 of those 18 control codes. The Set Attribute (SA)SCS control code is the only code supported by the IBM 3287 that HP printers do not support.
The SA control code is an extension of the SCS data stream and is considered an option by IBM. Also considered optional SCS extensions are the Structured Field and Attribute Processing (SFAP)features. SNA IMF does not support these options.
