105
Notice that your printer receives decimal code 13 (hex OD)
together
with hex OA, which is really decimal 10. In addition,
your printer does not receive decimal code 26 (hex 1A).
Your printer
prints
16 hex numbers
per line, printing
the
characters
on the right hand side. If it receives less than 16, it
sits in a holding pattern, awaiting more data. Taking the printer
off line dumps the characters
to the paper.
To debug a program quickly, just use the hex dump capabili-
ty. Appendix B will help you translate the hex codes to ASCII
equivalents.
