Patch #1, 6 Sep 92

This patch will correct a minor bug with the external protocol option
(when running under SVR3.2) that prevented Pcomm from detecting the
death of the child process.

The rather large size of this patch is do to the numerous changes to the
Doc.me file.

------------------------------------------------------------------------------
			     Pcomm version 2.0
				 18 Jul 92

Compatibilities with v1.2:

	The pcomm.modem and pcomm.param support files under v1.2 are not
	compatible with the new release.  There is a shell script called
	Convert.sh that will convert these files to the new format.

	The Script/TTY field of the dialing directory is now called
	the Auxiliary field.  It now has three functions...
		1) to specify a script to be played
		2) to force a particular TTY to be selected
		3) to select a modem configuration

Things that have changed:

        This version of Pcomm requires a pseudo-tty driver and System V
        poll() or Berkeley select().  Pre-SRV3.2 versions of AT&T Unix
        are out-of-luck...  sorry.

	There is a shell script called Configure.sh that will help you
	to configure Pcomm correctly for your system.  I've added a
	Q_and_A file to provide help on diagnosing problems.
	
	There is no longer a "pcomm_input" program, those functions are
	now supported by the use of multiplexed I/O within the "pcomm"
	program.  The external "modem_break" command has been removed.
	You might want to "search and destroy" those binaries.

	A new external command called "pcomm_cmd" has been added to
	allow "true" scripting capabilities.  There is a manual page for
	pcomm_cmd that further describes its features.

        Each dialing directory entry can specify a modem configuration
        via the newly renamed Auxiliary field.  This allows you to
        tailor the modem to match what is expected at the other end of
        the connection.

        Pcomm now supports DTE baud rates up to 38400 plus the odd-ball
        "connected" baud rates for V.32bis (7200, 12000, and 14400).

Future directions:

	Add zmodem as an internal protocol, since Omen Technologies
	deliberately broke sz/rz so that it wouldn't work from inside 
	another program.

        Add the ability to "dial into" a machine via a network LAN
        rather than the serial port.
