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 for EtherLite and SCSI Terminal Server. 

Note: Not all operating systems support both EtherLite and SCSI Terminal Server.

Device Information

Dial-In:
EtherLite

ttyNyz

  • tty is constant.

  • N is constant, and always uppercase for Dial-In connections.

  • y is the unit number, which is the numerical identifier 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 third port on EtherLite unit #2.

Dial-Out:
EtherLite

ttynyz

  • tty is constant.

  • n is constant, and always lowercase for Dial-Out connections.

  • y is the unit number, which is the numerical identifier 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 third port on EtherLite unit #2.

Dial-In:
SCSI Terminal Server

ttyXyz

  • tty is constant.

  • X is an uppercase letter from C-J, which identifies the SCSI bus. C specifies the first (or only) SCSI bus, D specifies the second, etc.

  • y is the SCSI ID number for the SCSI Terminal Server.

  • z is the port number. Use 0-9 for ports 1-10; use a-v for ports 11-32.

  • A ttyXyz device is usually a dial-in device. These devices wait for the carrier signal before opening.

Example: ttyC23 is the third port on a SCSI Terminal Server set to SCSI ID #2, connected to the first SCSI bus.

Dial-Out:
SCSI Terminal Server

ttyxyz

  • tty is constant.

  • x is a lowercase letter from c-j, which identifies the SCSI bus. C specifies the first (or only) SCSI bus, D specifies the second, etc.

  • y is the SCSI ID number for the SCSI Terminal Server.

  • z is the port number.

  • A ttyxyz device is usually a dial-in device. These devices do not wait for the carrier signal before opening.

Example: ttyc23 is the third port on a SCSI Terminal Server set to SCSI ID #2, connected to the first SCSI bus.
