UDP and TCP devices in the "root" (/) file system
The root
(/) file system under the directory of /dev/xti
will now hold two device drivers named udp and tcp.
Both of the drivers are character special files (*CHRSFs) and are created during the first initial program load (IPL). The User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) device drivers are used to open a connection to the UDP and TCP transport providers. Both of these drivers are user devices and receive a new device major number. They also have cloned open operations, which means that each open operation obtains a unique instance of the device. The use of these devices is only supported in the IBM i Portable Application Solutions Environment (PASE). The following table contains the objects that will be created and their properties.
| Path name | Type | Major | Minor | Owner | Owner data authorities | Group | Group data authorities | Public data authorities |
