Setting Up a Bidirectional Modem
To set up a bidirectional modem, you need information for these variables.
port-name— The port to which the modem is connected (typically, ttya or ttyb).
svctag— The name of the port monitor service (for Sun systems, zsmon).
port-device-name— The name of the device for the port (typically /dev/cua/a or /dev/cua/b).
short-port-device-name— The name, without the complete path, for the port.
modem-label— The entry in the /etc/ttydefs file that is used to set the proper baud rate and line discipline.
modem-type— The type of the modem from the /etc/uucp/Dialers file. For example, the type for a Hayes modem is hayes.
Use the following steps to connect a modem.
Halt the system.
Make sure hardware carrier detect is disabled.
At the OpenBoot PROM prompt, type setenv ttyb-ignore-cd=false and press Return.
Reboot the system.
Connect the modem and make sure any modem switches are set to allow bidirectional use.
Use the SMC Devices and Hardware/Serial Ports tool to configure a serial port for a modem.
See the Solaris Management Console Tools book for detailed instructions.
