### Device Names

Use this information to find out how the devices on your Digi adapter are named in SCO OpenServer. The naming conventions differ for different adapter types-- choose the link below that corresponds with your adapter.

- Device Names: C/X, EPC/X and Xem Systems
- Device Names: Xr Adapters
- Device Names: Xe Adapters

#### Device Names: C/X, EPC/X and Xem Systems

Format used for device names:/dev/ttycp, /dev/prcp

tty | Base name
pr | Base name for DigiPRINT devices
c | Concentrator/EBI Module ID (a-z, A-Z) Lowercase letters denote non modem control devices. These devices do not require DCD to be asserted before they can transmit data. Uppercase letters denote modem control devices. These devices require DCD to be asserted before they can transmit data.
p | Port number on the specified concentrator or EBI module (01-64). Systems with a large number of ports may have to use some Concentrator/EBI module ID letters more than once; when this occurs, ports on the first concentrator or module to use an ID letter will be numbered 01-16, ports on the second will be numbered 17-32, etc.

##### Examples:

Port 4 on Concentrator 2 will be /dev/ttyb04. The same port with modem control is /dev/ttyB04. The corresponding DigiPRINT devices are /dev/prb04 and /dev/prB04. If there are 28 concentrators/EBI modules, the 28th will also be assigned the ID letter "B"; Port 4 on Concentrator 28 will have the names /dev/ttyb20, /dev/ttyB20, /dev/prb20 and /dev/prB20.

#### Device Names: Xr Adapters

Format used for port names: /dev/ttyrbp, /dev/prrbp

ttyr | Base name
prr | Base name for DigiPRINT ports
b | Adapter number (1-4)
p | Port Identifier (a-p, A-P) Lowercase letters denote non modem control ports. These ports do not require DCD to be asserted before they can transmit data. Uppercase letters denote modem control ports. These ports require DCD to be asserted before they can transmit data.

##### Example:

Port 4 of Adapter 2 is /dev/ttyr2d. The same port with modem control is /dev/ttyr2D. The corresponding DigiPRINT devices are /dev/prr2d and /dev/prr2D.

#### Device Names for: Adapters

Format used for port names:/dev/ttyibp, /dev/pribp

ttyi | Base name
pri | Base name for DigiPRINT ports
b | Adapter number (1-4)
p | Port Identifier (a-p, A-P) Lower case letters denote non modem control ports. These ports do not require DCD to be asserted before they can transmit data. Upper case letters denote modem control ports. These ports require DCD to be asserted before they can transmit data.

##### Example:

Port 4 of Adapter 2 is /dev/ttyi2d. The same port with modem control is /dev/ttyi2D. The corresponding DigiPRINT devices are /dev/pri2d and /dev/pri2D.
