<strong>System</strong> Terminal window<br />

The <strong>System</strong> Terminal window displays all system events as they occur. It also gives<br />

you direct access to any overlay.<br />

For Ethernet or PPP connections, each active <strong>System</strong> Terminal connection requires a<br />

pseudo-TTY (PTY) port. PTYs are software-only I/O ports. The <strong>System</strong> Terminal and<br />

Maintenance Windows applications use these ports to access the overlays.<br />

Ethernet and PPP are available only for X11 Software Release 23 and above with<br />

packages 296 and 243 equipped.<br />

Configuring a pseudo-TTY port<br />

OTM applications require that you configure a pseudo-TTY (PTY) port on the system<br />

for access to the overlays. TTY ports differ from PTY ports in that a TTY port has<br />

physical hardware that interfaces with an external device. A PTY port is a software<br />

emulation of a serial port connection to a device or application through an IP network.<br />

Physical TTY ports do not need to be installed to support PTY ports. There is no<br />

connection between these two types of ports. The primary requirement is that you have<br />

a device number (DNUM) available for configuring the PTY port.<br />
