com:  #56 ------------  MIT/ISI COMM GROUP
com:  #56 COMMREAD ME   Release letter for MIT/ISI communications package
com:  #56 COMMMSGS DOC  Details about IBM Async port & BIOS and MIT/ISI comm.
com:  #56                package.
com:  #56 LPT_PKG  ASM  An interrupt driver and interface package for the
com:  #56                line printer.  It uses the same circular buffer
com:  #56                scheme as the COM package.  It is primarily intended
com:  #56                for special applications, such as printing graphics.
com:  #56 INT_PKG  ASM  These routines save and restore interrupt vectors.
com:  #56                "Chained" vectors are not directly supported.
com:  #56                Vectors may be saved/restored in one of three ways:
com:  #56                DOS 1, DOS 2, or no DOS.
com:  #56 EXMEM    ASM  These routines provide additional physical memory
com:  #56                access.  Memory is accessed with 20-bit addresses.
com:  #56                All of physical memory may be accessed, regardless
com:  #56                of the programming "model".
com:  #56 EXIO     ASM  These routines provide additional machine I/O functions
com:  #56                beyond the Lattice-supplied inp() and outp().  The new
com:  #56                functions solve certain interrupt-and DMA-related
com:  #56                problems in devices which require multi-I/O control
com:  #56                sequences.  These routines are not used by the rest of
com:  #56                the distribution at present, but may be used in the
com:  #56                future.
com:  #56 COM_PKG  ASM  The interrupt-driven COM package.
com:  #56 COM_PKG1 ASM  Provides a library of serial port routines.
com:  #56 BMACTST  ASM  This program tests the BMAC macros.
com:  #56 TSTLPT   C    A test program for LPT_PKG.
com:  #56 TSTINT   C    A test program for INT_PKG.
com:  #56 TSTEXMEM C    This program tests the routines in EXMEM.  For complete
com:  #56                confidence, the test should be run under the control
com:  #56                of a debugger to verify the results.
com:  #56 TSTCOM   C    A test program for the COM package.  Allows the IBM PC
com:  #56                to act like a glass TTY connected to a host via COM1:.
com:  #56                This program is more useful when you are running the
com:  #56                ANSI terminal driver.  There is no protection against
com:  #56                DOS character traps (control-C, etc.).
com:  #56 TSTCOM2  C    A second test program for the COM package.  It
com:  #56                allows the IBM PC to approximate an (expensive)
com:  #56                null modem between COM1: and COM2:.
com:  #56 TITLE    MAC  These macros provide functional replacements for
com:  #56                the standard TITLE and SUBTTL macros.  A table of
com:  #56                contents appears in the symbol table at the end
com:  #56                of an assembly listing.
com:  #56 DOS      MAC  This file comes from the Lattice C distribution.  It
com:  #56                defines which programming "model" is being used, for
com:  #56                the benefit of assembly routines.  It defines the
com:  #56                PSECTs used for code and data.  Edit this file to
com:  #56                select your programming "model".  This version of
com:  #56                DOS.MAC fixes a bug in the standard Lattice C version.
com:  #56 BMAC     MAC  Assembly language macros which encapsulate the sub-
com:  #56                routine call interface.  The macros define names for
com:  #56                subroutine arguments and temporary variables on the
com:  #56                stack.  This version interfaces with Latice C (aka
com:  #56                Microsoft C).  Both large small programming "models"
com:  #56                are supported.  A separate version of BMAC could be
com:  #56                created to interface to IBM Pascal, if desired.
com:  #56 TRUTH    H    Contains type definitions for the bool (boolean)
com:  #56                data type.
com:  #56 EXMEM    H    This file defines the p_addr (physical address)
com:  #56                data type, and defines the return values of some
com:  #56                of the EXMEM functions.
com:  #56 BEAUTY   H    A set of macros and type definitions which enhance C
com:  #56                program portability and reliability. The macros define
com:  #56                an enhanced set of character and integer data types.
com:  #56                Edit this file to select your programming "model"
com:  #56                (long pointers vs. short pointers).
com:  #56 GLASSTTY PAS  Simple dumb terminal for IBM PC.
