System Startup, Configuration, and Shutdown Reference Manual (32650-90892)

Appendix A 195
Using the Access Port (AP)
Configuring the Console
CAUSE: The first two characters entered in a command line for the AP command
interpreter are not an AP command. Help displays all legal commands.
MESSAGE: Expecting “Y” or “N” (APERR 11)
CAUSE: The AP is expecting one of the letters Y or N, in either uppercase or lowercase, as
the reply to the query displayed on the screen.
MESSAGE: Expecting “H” or “L” (APERR 12)
CAUSE: The AP is expecting one of the letters H or L, in either uppercase or lowercase, as
the reply to the query displayed on the screen. H stands for high, and if chosen, causes the
specified signal to be set to the high voltage level, which is nominally +9 Volts referenced to
ground. L stands for low, and if chosen, causes the specified signal to be set to the low
voltage level, which is nominally -9 volts referenced to ground.
MESSAGE: Command may not be executed by a remote user. (APERR 13)
CAUSE: The command entered is a valid AP command, but is intended for use from the
local console port (port T0) only. No action has been taken.
MESSAGE: Your selection is outside of the legal range. (APERR 14)
CAUSE: Either numeric data has been entered when alphabetic input is expected (or vice
versa), or the value of numeric data entered is outside of the permissible range of values.
MESSAGE: Command may not be executed by a local user. (APERR 15)
CAUSE: This command is a valid AP command, but is intended for use from the remote
support modem port (port T1) only. No action has been taken.
MESSAGE: Expecting “S” or “M” (APERR 16)
CAUSE: The only permissible input at this time is the letter S for single or the letter M for
multiple. They may be entered either in uppercase or lowercase.
MESSAGE: Syntax error. (APERR 17)
CAUSE: Any error other than those covered by error messages APERR 18 and APERR 19
when using the DM, AM, DD, or AD commands, causes this error message.
MESSAGE: Illegal hexadecimal entry. (APERR 18)
CAUSE: If any of the hex parameters entered with the DM, AM, DD, or AD commands are not
valid hex numbers, this error message is be output.
MESSAGE: Illegal address or address range. (APERR 19)
CAUSE: Attempting to address outside the legal range of addresses with the DM, AM, DD, or
AD commands causes this error message to be given.
Informational Messages
MESSAGE: AP self-test passed. (APMSG 01)
CAUSE: AP self-test was executed, and it has passed. The message is accurate in almost all
cases; however, it is possible that the message will appear without the test having
executed to completion. This case can be detected by observing whether the full
complement of subtests has been executed in the proper order.
