Device and console names
Each terminal device driver can provide a single console device.
Table 1 lists the terminal device drivers with the corresponding device names and console names.
| Device driver | Device name | Console name |
|---|---|---|
| SCLP line-mode terminal device driver | sclp_line0 | ttyS0 |
| SCLP VT220 terminal device driver | ttysclp0 | ttyS1 |
| 3215 line-mode terminal device driver | ttyS0 | ttyS0 |
| 3270 terminal device driver | 3270/tty1 to 3270/tty<N> | tty3270 |
| z/VM® IUCV HVC device driver | hvc0 to hvc7 | hvc0 |
| virtio-console device driver | hvc0 to hvc<n> | hvc0 |
As shown in Table 1, the console with name ttyS0 can be provided either by the SCLP console device driver or by the 3215 line-mode terminal device driver. The system environment and settings determine which device driver provides ttyS0. For details, see the information about the conmode kernel parameter.
Of the terminal devices that are provided by the z/VM IUCV HVC device driver only hvc0 is associated with a console.
Of the 3270/tty<N> terminal devices only 3270/tty1 is associated with a console.
