NOTE:
The pinout above indicates the active signals that are used when communicat-
ing with external DTE or DCE equipment via a NetPerformer serial interface.
These HD-26 cables are custom and proprietary to the NetPerformer. The
information in this table is not sufficient to manufacture a working cable that
can interoperate with the serial port on the NetPerformer unit.
