RealPort Setup
3-7
12.
To configure dial-in logins on the modem port, you must have a port monitor running. You can
use an existing port monitor or add a new one. This example assumes that you will add a new
one.
Run sysadm and choose Device, Port, Port Monitor, and then Add. Use the defaults (just press
enter) for all the prompts except "Port monitor tag" where you will enter a name for the port
monitor. In this example, modem is used for the name.
When this is completed the port monitor should be added to the system.
13.
Add the port service for this port.
In sysadm go to Device > Port > Port Service > and then choose Add.
You are prompted for several responses; in most cases you can accept the default by pressing
enter, except for the following.
For Controlling port monitor, enter the name of the port monitor, modem.
For Port service tag, enter the device name,
tty17
.
For Path name of terminal device, enter the full path of the device,
/dev/tty17
.
For TTY Definition Label, enter a modem definition label such as
M9600
.
For Bidirectional?, enter
yes
if you want to use the modem for dial-out or to connect to the
modem with cu to send modem commands.
When this is completed the port service for this port should be added to the system.
You can change any port service settings later with sysadm by choosing Modify in the Port Ser-
vice menu.
14. If you want hardware flow control on the port, this can be configured in the /etc/ttydefs file for
dial-in, or with stty-ncxa for dial-in or dial-out. For example,
stty-ncxa rtspace ctspace /dev/tty17
15.
The port is now configured for dial-in and, if you answered yes to "Bidirectional?" in the port
service configuration, for dial-out use.
To dial-out you will need to first run stty-ncxa to set forcedcd to connect to the modem:
stty-ncxa forcedcd /dev/tty17
When you are done with dial-out, you must reset -forcedcd:
stty-ncxa -forcedcd /dev/tty17
If you forget to reset -forcedcd, logins will not be terminated when the modem drops carrier.
