Compaq AlphaServer ES45 1B User Manual

Firmware 5-73
5.14.23 tt_allow_login
The tt_allow_login environment variable enables or disables login to
the SRM console firmware on alternative console ports. “Login” refers
to pressing the Return or Enter key to activate the console device.
If the console environment variable is set to serial, the primary console device
is the terminal connected through the COM1 port. The set tt_allow_login 1
command lets you activate a console device through COM2 or a VGA monitor.
The set tt_allow_login 0 command disables console activation through alter-
native ports. You might want to disable console access to COM2 as a system
security measure or if you want to use COM2 as an “application only” port.
Syntax
set tt_allow_login value
The options for value are:
0
Disables login through the COM2 port or the VGA monitor.
1 (default)
Enables login through the COM2 port or the VGA monitor.
Example
In the following example, the primary console device is set to the terminal con-
nected through the COM1 port. Then the set tt_allow_login 0 command is
used to disable logins through either the COM2 port or a VGA monitor.
P00>>> set console serial
P00>>> init
.

P00>> set tt_allow_login 0
