Hex Code Printout - IBM 6400 Setup Manual

Hex Code Printout

A hex code printout (or hex dump) lists each ASCII/EBCDIC data character
received from the host computer, along with its corresponding two-digit
hexadecimal code. Hex dumps can be used to troubleshoot some types of
printer data reception problems.
To convert an ASCII/EBCDIC character to its corresponding hex code (or
vice-versa), refer to the ASCII code chart in the 6400 ASCII Programmer's
Reference Manual, or the EBCDIC code chart in the 6400 Coax/Twinax
Programmer's Reference Manual.
Each printable character prints both as its assigned symbol and as its hex
equivalent. Each nonprintable character prints both as a period (.) and as its
hex equivalent.
When using a parallel interface, the letter "p" before a hex code indicates an
active Paper Instruction (PI) line and a blank space before a hex code
indicates an inactive PI line.
To obtain a hex code printout, perform the following steps.
