ERROR MESSAGES
All error messages are preceded by an audible "beep" on the
console.
ERROR: NO CHARACTER RECEIVED, POLLED MODE, TTY# FAILED

This is the first test performed. No character
was transmitted between the ports in a polled-mode
transmissi.on. All possible ASCII characters f:.--om

ports was initiated. If the error count 103 ze:o

error count represents the number of times that
the character received differed from the character
transmitted." The interrupt mode test contin~~3
until a character is input on the console.
