Where n = 0, 1, or 2
The syntax for modifying the timer via the sysconfig command is as follows:
# sysconfig -r ace dcd_timer=n
Where n = 0, 1, or 2
Note that by modifying the value with the sysconfig command, the
setting is lost when the system is rebooted. To preserve the setting across
reboots, edit the /etc/sysconfigtab file.
2.2.1.3 Setting the Console Environment Variables
The COM1_MODEM, COM1_FLOW, and COM1_BAUD console environment
variable settings must be equivalent to the getty or uugetty settings
used when you created your system file entries for the modem.
Consult your hardware documentation for information on how to set the
console environment variables. Typically, the variables are set when the
system is shut down and in console mode, as shown in the following
example:
>>> set COM1_MODEM ON
>>> set COM1_FLOW SOFTWARE
>>> set COM1_BAUD 9600
Valid settings are as follows:
• COM1_MODEM: ON or OFF
• COM1_FLOW: NONE, HARDWARE, SOFTWARE, BOTH
• COM1_BAUD: Consult your system hardware documentation.
Note that if you change the baud rate, flow control, or modem setting (for
example, using the getty command), the change will be propagated down
to the console level and the environment variables will change
automatically.
2.2.1.4 Verifying the Modem Setup
Dial the remote system and obtain a log-in prompt or console prompt, if the
system is not booted. Log out or disconnect and ensure that the line hangs
up correctly. Dial in again to ensure that you can reconnect.
2.2.2 Initiating a Console Port Connection

different methods. A tip, kermit,orcu connection can be initiated from a
