The HomeWriter- has a special feature that makes it easy for

experienced printer users to find the causes of problems. Called the

hex code dump mode, it gives a printout of exactly what codes reach

the printer.

Turn on this mode by turning on the printer while holding down

both the FF and LF buttons. The printer responds by printing the

words HEX CODE DUMP (CURSOR UP MODE). Then, when you

run a program, either an applications program or one you have writ-

ten in any programming language, the HomeWriter- prints one or

more lines. Each line has two parts: the hexadecimal codes (up to 16

numbers) and the guide section (16 characters at the end of each line).

The hexadecimal numbers are the codes received by the printer, and

the guide section helps you find a certain place in the list of codes. Each

character in the guide section corresponds to one of the codes. If the

code is for a printable character, that character is printed. If the code is

for a non-printable character (such as the codes for line feed,

expanded printing, or carriage return), a dot is printed.

Therefore, if you run the following BASIC program while your

HomeWriter- is in the hex code mode, you produce the printout

you see below it. The printer will print all but the last line and then

stop. Press the ON LINE button to make the printer print the last line.

You don’t have to understand hexadecimal numbers to use them. In

Appendix A you can find the decimal equivalent of each hexadecimal

number, and Appendix B gives the meaning of the non-printable

codes. An explanation of this printout will put you on the right track

for using the data dump mode.
