Network I/O Error Codes

167Bug returns an error code if an attempted network operation is
unsuccessful.

Multiprocessor Support

The MVME167 dual-port RAM feature makes the shared RAM
available to remote processors as well as to the local processor. This
can be done by either of the following two methods:
Either method can be enabled/disabled by the ENV command as
its Remote Start Switch Method (refer to Appendix A).

Multiprocessor Control Register (MPCR) Method

A remote processor can initiate program execution in the local
MVME167 dual-port RAM by issuing a remote GO command
using the Multiprocessor Control Register (MPCR).
The MPCR, located at shared RAM location of $800 offset from the
base address the debugger loads it at, contains one of two
longwords used to control communication between processors.
The MPCR contents are organized as follows:
Base Address + $800
The Multiprocessor Control Register (MPCR) Method
The Global Control and Status Register (GCSR) Method
