DEC LA120 Emulation
The " f" at the end of the escape sequence represents the final character. It terminates the sequence, and specifies the function to be performed.
Spaces are used when documenting escape sequences to increase readability. The spaces within the sequences are for readability only; they are not part of the sequences themselves. Characters that appear in italics (such as "n" and "f" above) are not sent to the printer as is; they are used as a place holder indicating that some value must be supplied.
Multiple character strings without intervening spaces typically represent control codes. For example, BS is the Backspace control code (08 hex), not the two characters "B" and "S" (42 and 53 hex). An ASCII Control Code Table is contained in the appendices for your convenience. If you have any doubt about how to interpret a documented control code or escape sequence, refer to the hex representation in the provided example. This should clarify any ambiguity. The examples may also be helpful when analyzing a hex dump (see chapter 8) printed by the printer.
Some escape sequences refer to the active column or active line. The active column is the column where the next character will be printed. Printing a character or a space will increment the active column. The active line is the line where the next character will be printed. A line feed will increment the active line. Column and line numbers begin at one, not at zero. Keep this in mind when setting tabs, margins, etc.
