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 these drivers are character special files (*CHRSFs) and are created during the first initial program load (IPL). The UDP and 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 opens, which means that each open obtains a unique instance of the device. The use of these devices is only supported in i5/OS™ Portable Application Solutions Environment (PASE). The following table contains the objects that will be created and their properties.
