#protocol ⇒ Integer

Returns connection protocol (0, 1, 3, or 4) 0 Compatibility with peers other than OS/390®. (default) 1 Enhanced package checking for Linux peers. 3 For compatibility with OS/390 or z/OS peers. 4 For MPC connections to VTAM on traditional mainframe operating systems.

#read_channel ⇒ String

Most I/O devices on a s390 system are typically driven through the channel I/O mechanism.

The s390-tools provides a set of commands for working with CCW devices and CCW group devices, these commands use a device ID which is the device bus-ID

The device bus-ID is of the format 0.<subchannel_set_ID>.<devno>, for example, 0.0.8000.

The CTCM device driver requires two I/O subchannels for each interface, a read subchannel and a write subchannel

Returns:

  • (String) —

    read device bus id
