Appendix A

ASCII Codes and Character Sets

This appendix provides information about the ASCII codes used on the P-80 printer. The first section shows the available codes between 0 and 32 with their decimal and hexadecimal numbers, abbreviations, and the control keys associated with each code. The first section also displays, in ASCII order, the decimal and hexadecimal numbers and a printout of each character in the USA Roman font. The characters for the Roman font that make up the USA character set occupy ASCII positions 33 through 126.

The second section shows the international characters available on the P-80 and their corresponding ASCII codes. The international characters can be selected by changing the DIP switches as mentioned in Chapter 1, or they can be selected by using <ESC>“R” (see Appendix B). The second section also shows the graphics character set. The graphics character set occupies ASCII positions 128 through 159.

Included in the second section are some special characters in the USA character set that are worth noting. These characters may not appear on your computer’s keyboard but you can access them by using the appropriate ASCII code.
