Format: The Set Buffer Address order is formatted as follows: Set Buffer Address Hex 11 Row Address Hex 01 Column Address Hex 01 Row and column addresses begin with 1. However, the computer accepts column address hex 00 and translates it to column 1. Start of Field Description: The Start of Field (SF) order defines input and output fields. If an input field is being defined, it also resets any pending AID byte and locks the keyboard. Note: Although this order can be used for output fields, it is not recommended because it degrades performance. Use the Set Buffer Address order instead.

You can also insert several control words between the format and attribute portions of the SF order, but these control words are not required.
