Using the AP Help Facility
Obtain online help by entering either HELP or the abbreviated command, HE.
The command issues the following display:
CM>HELP
Access Port Revision xxx m.d.y
CA Configure system remote support modem port.
CO Enter console mode.
DI Disconnect line to remote console terminal.
DR Disable access by a remote console terminal (enables session
access).
DS Disable display of system status line during console mode.
ER Enable access by a remote console terminal (disables session
access).
ES Enable display of system status line during console mode.
HE Display this screen.
RS Stop all processing, initiate SPU Self-Test, load software
from load device if enabled for autoboot.
SE Transfer remote terminal from console/control to session mode.
TA Initiate Access Port Self-Test.
TC Transfer processor execution to operating system specific routine.
TE Send message between local and remote console terminals.
In the preceding display, xxx is the number of the revision of the operating firmware contained on the AP and
m.d.y is the month, day and year the firmware revision was released. These identifications are necessary to
manage ROM updates in the field if they become necessary.
Returning from Control Mode to Console Mode
The access port command, CO, returns the console from control mode to console mode. Once returned to
console mode, the system console operates in its normal session mode. This command does not generate
messages.
Configuring the Access Port
Issuing the AP command, CA, allows either the local or remote console operator to reconfigure the baud rate
for the remote support modem port, the setting of the T1 RATE line, and the system identification. The AP
accepts any configuration, making no judgment on the validity.
RS Stops all processing, initiates SPU self-test, and loads
software from load device if enabled for autoboot.
SE Transfers remote terminal from console/control mode to
session mode.
TA Initiates access port self-test.
TC Transfers processor execution to operating-system-specific
routine. Initiates a system soft reset.
TE Sends messages (up to 80 characters) between local and
remote consoles.
