The Solaris system administration utility, admintool, can be used to configure RealPort devices.
Note: In order to use admintool, The Digi devices need to be linked to devices in /dev/term and /dev/cua. These links are normally created when the driver is installed. If these links are not there, they can be created manually.
Access admintool through a window interface, or entering this command at a root prompt:
admintool
From the admintool window, select Browse>Serial Ports.
Select a device.
Select Edit > Modify.
Configure the port as needed.
