Figure C-1. Hexadecimal codes in order
For example, in the lines below, which are the first two lines of the
printout of the test program run with IBM PC BASIC, you can see
that in this case BASIC adds hex OA, which is the code for line feed,
after hex OD, the code for a carriage return. You will also notice that
the ram does not send hex 1A, which is decimal 26. Both of these
characteristics are discussed in the next section.
