  	"Unpacking" Instructions for Professional-YAM
						Rev Jun 7 1995
			Version 18.18

***************************
 ****  W A R N I N G  ****	Don't throw away your SNP Card!
***************************

Instructions for Hard Disk Users:
Place this disk in the A: drive and change directory to the hard disk
root directory.  Then type "a:install".  Be sure to have your
Serial/Number/Password (SNP) card handy.

Instructions for Floppy Disk Users:
Place this disk in the A: drive and a blank fomatted disk (perhaps
with DOS on it) in the B: drive, and log into the B: drive.  Then
type "a:floppy".  Be sure to have your Serial/Number/Password (SNP)
card handy.

***************************************************************************
Remember, only Omen's "usq" program decrypts Demand Upgrade encrypted files.
***************************************************************************

**** Script writers may find the THEDRAW program useful for designing menu
and other screens which can be "typed" by TurboDial scripts.  THEDRAW is a
shareware program available on many fine systems.

TurboDial 2.41 adds the "fc" string parameter which returns the
next modem character as a decimal number in the range 0 to 255.
A timeout (200 ms) returns -2.

18.18 Added support for the Texas Insturments TL16C550C ACE with
AUTO-FLOW control.  This chip is identified as type 4.

18.15 adds support for the Startech ST16C650 FIFO UART.  This
chip includes 32 byte FIFO registers.  When hardware handshaking
is used, logic is activated to provide on chip flow control with
an instant response independent of interrupt latency from disk
drivers, TSR programs or other causes.  An ST16C650 is identified
as TYPE 3.

18.14 The zmrxesc and zmtxesc strings now accept "?" to escape the
all ones character FF.

18.11 The "queue clear" command now resets the pointer to the first
queue element.

The zmodem k, K, and J numeric parameters have been added to provide
better control over SMARTDRV operation (PCDOS only).  If you are
getting LSR 02 errors when SMARTDRV dumps its buffer, set the zmodem k
parameter the the number of kilobytes to be written between SMARTDRV
buffer flushes.  If the I numeric parameter is set, it will take
precedence over how often SMARTDRV is flushed.

Printer controller mode now passes all characters if vt100 emulation
is not selected.  (Vt220 specs require NULL, XON and XOFF to be filtered.)
If the ena -8g command is given, all 8 bits are passed to the printer.
When printer controller modes is used, the host system should not resume
output when a second XOFF is received.

18.08 Enhancements for latest CompuServe B+ CRC-32 and "MobyKermit".  Kermit
downloads can use the latest C-Kermit speed options given below.  Kermit
autodownloads have been redesigned for proper operation with new as well as
classic Columbia Kermit programs.

set buffers 25090 25090
set window-size 5
set send packet-length 5000
set receive packet-length 5000
set block 3
set flow none
set handshake none	(or use hardware flow control)
set control unprefixed all
set control prefixed 0 1
set transfer cancellation off
set file type binary
set delay 0

When receiving from C-Kermit 189 Pro-YAM is virtually as fast as Columbia
Kermit with the added benefit of rapid automatic downloads with automatic
dialect recognition.  To support the latest Columbia Kermit, Pro-YAM no
longer ignores control characters within packets unless the -M option
is given.  It will now be necessary to use the -M option in some mainframe
and/or network Kermit applications (kermit rb -M).

When sending with Kermit, control prefixing can be minimized with the
"kermit sb -m" option (MobyKermit).  The user must experiment to determine if
the receiving program will accept this new Kermit sub-dialect.


18.05: The portx command now works with IRQ's up to 15.  An example card
that supports these higher IRQs is the $99 "WinSport II" from Boffin LTD
612-894-0595.  This card has two NS16550AFN FIFO UARTS and also supports
MobyBaud (18.432 MHz clock).

The "D" numeric parameter has been removed; its function is provided by
the optional third argument to the "portx" command.
	portx 3e8,15,57600 speed 200000
Selects a comm port with a base address of 3e8 using IRQ15 and the 18.432
MHz clock option on the Boffin Electronics "WinSport II" 2 port serial board.

18.04: The "handshake ax" command takes the low order 5 bits of the first
letter of the command (usually "a") and writes them to the 8250/16550 UART
Modem Control Register.  This hack is specific to PCDOS flavors.
A typical application is "ha ax" which raises Data Terminal Ready (bit 0)
but turns off Request To Send, useful for interfacing to the Radio Shack
Micronta Cat. No. 22-182 LCD Digital Multimeter with PC Interface.  This
instrument uses an optical coupler and will not communicate unless DTR is
ON and RTS is OFF.

************ Upgrade Support for Professional-YAM Versions ***************

Technical questions should be put by voice to Omen Technology
Inc, to give us the benefit of the feedback.

Omen Technology (Chuck Forsberg) can be reached a number of ways:

  Voice:	503-621-3406

  Modem:	Telegodzilla: 503-621-3746 11400, 9600, 2400, 1200 b.p.s.
                This is the system to call for "demand upgrade"; the
                latest versions of Pro-YAM are stored in the subdirectory
                "upgrade" in encrypted form (See Chapter 6) along with the
                current copy of this file.  The popular Demand Upgrade
                files are also available on BIX, CompuServe's IBMCOM Special
                Interest Group, and GEnie page 615 library.

		***************************************************************
		**  Encrypted upgrade files MUST be unsqueezed/decrypted     **
		**  with Omen's "usq" program; other unsqueezers won't       **
		**  decode encrypted files.                                  **
		***************************************************************

		Current versions of the manual are provided in the encrypted
		file yamman.q. On TeleGodzilla, they are in the upgrade/man
		sub directory.  This is a long file; download it with ZMODEM
		so you can recover from a disconnect.

	To download the latest YAM version from Telegodzilla,
	follow these steps:

        1.  Dial in, preferably at 14400 (v.32bis) or 9600 bps.
        You can use the "omen" entry in the supplied phones.t
        file: "call omen" (Use the best long distance carrier
        available, the local exchange is getting long in the tooth.

        2.  Telegodzilla will announce itself after several seconds, at
        the correct speed.  Enter your name.  EXAMPLE: "Susie Thunder"

	3.  Change to the upgrade directory: "cd upgrade"

	4.  List the files, newest first:  "dirt"

	5.  List the NEWEST.MEQ file to see if any of the changes interest
	you (they might not!):	"type newest.meq"  Hit Ctrl-X when you've
	seen enough.

	6.  If you want to download the newest version, tell Telegodzilla
	to send the latest YAM files:	"sz yam.eqe read.meq"

	7.  Once the transfer has started, you can type ALT-Q to make
	YAM hang up when the file transfers have been completed.  Or, you
	can issue other commands after the files have been transferred.

        8.  Only Omen's "usq" program will decrypt demand upgrade
        encrypted files.  The key file is included in your distribution
        diskettes, and must be present in the current directory..
		$ usq yam.eqe
	Make sure your old version of YAM is in a safe place until
	you have made certain the new version suits your needs.

Flavors for SCO SYS V Xenix are available for downloading in the
TeleGodzilla upgrade/scoxenix sub directory.  Consult the readx.me file in
that directory for info.  A flavor for 386 Unix (ISC, Microport, Bell Tech,
AT&T, Enix, etc.) is available in the upgrade/isc directory.  VAX/VMS and
OS/2 flavors are available in their subdirectories.
