PCL(4) | Kernel Interfaces Manual (VAX) | PCL(4) |
The pcl device provides an IP-only interface to the DEC CSS PCL-11 time division multiplexed network bus. The controller itself is not accessible to users.
The host's address is specified with the SIOCSIFADDR ioctl(2). The interface will not transmit or receive any data before its address is defined.
As the PCL-11 hardware is only capable of having 15 interfaces per network, a single-byte host-on-network number is used, with range [1..15] to match the TDM bus addresses of the interfaces.
The interface currently only supports the Internet protocol family and only provides “natural” (header) encapsulation.
