                      MIT/ISI Comm Package

We're releasing a new serial I/O package to the Info-IBMPC library.  It was
originally developed by John Romkey and Jerry Saltzer  of MIT.  I made some
modifications.  Craig Rogers has taken it  quite a bit further.  The package
is fully interrupt driven on  transmit, receive and error detection.  It will
run at 9600 baud,  and even faster if you don't plan on doing anything else.

Both my version and Craig's version are now in the library.  My  version is
pretty much the same as the one sent me by John  Romkey.  It has been conver-
ted to use Microsoft Pascal calling  conventions.  Only one serial port is
supported (COM1:).  The  package is in the file COM_PKG1.ASM.  A dumb terminal
program  that calls it, written in Pascal, is in the file GLASSTTY.PAS.
Craig Rogers' version uses a dozen files or so.  CONTENTS describes the
various files.  Both the complexity and flexibility of  this version come from
its ability to support multiple operating  systems, languages, and address
sizes.  Currently it supports  large and small model Lattice C, DOS 1.1 and
DOS 2.0 as well as a  stand alone mode.  Both COM1 and COM2 are supported
simultaneously.  A package is included for line printer support.  The
subdirectory contains a dumb terminal program and a null modem  program
written in Lattice C that call the package.

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