Device Names

Use the information on this page to determine which device to use for a particular Digi port.

During the driver installation, Digi devices are created in the /dev directory. There are two device types: dial-in and dial-out. The table below shows the device naming conventions.

Device Information

Dial-in

ttyNyz

  • tty is constant.
  • N is constant, and always uppercase for Dial-in connections.
  • y is the unit number, which is the numerical identifier, beginning with zero, assigned to each EtherLite unit as it is installed.
  • z is the port number. Use 0-9 for ports 1-10; use a-v for ports 11-32.
  • A ttyNyz device is usually a dial-in device. These devices wait for the carrier signal before opening.

Example: ttyN23 is the fourth port on the third EtherLite unit.

Dial-out

ttynyz

  • tty is constant.
  • n is constant, and always lowercase for Dial-out connections.
  • y is the unit number, which is the numerical identifier, beginning with zero, assigned to each EtherLite unit as it is installed.
  • z is the port number. Use 0-9 for ports 1-10; use a-v for ports 11-32.
  • A ttynyz device is usually a dial-in device. These devices do not wait for the carrier signal before opening.

Example: ttyn23 is the fourth port on the third EtherLite unit.
