Subject: new BDS C hardware customization scheme

In response to suggestions made by Fylstra/Rconn et. al., I have adopted
a new method of configuring the I/O port interface for BDS C programs
that require direct access to I/O ports. Note that pre-1.50 BDS C packages
had one header file, BDSCIO.H, containing all definitions; v1.50 has
BDSCIO.H for general definitions and HARDWARE.H for hardware-specific
definitions. The new port interface is in HARDWARE.H. TELED.C, the all-in-
one modem program and text editor (a real cute hack, it is) has been
modified to use the new header files and port access scheme. File summary:
       AR34:cpm;bdscio 50h     -- BDSCIO.H
       AR34:cpm;hware 50h      -- HARDWARE.H
       AR35:cpm;teled 12c      -- TELED.C
Feedback is welcome.
