This document describes the Lantronix Modem Redirector for Windows 95/NT
software release.

This document is divided into the following sections:
o New Features
o Requirements to run the redirector.
o Packages that have been tested against the redirector.
  - Windows 95
  - Windows NT
o Fax modem table


New Features
============
o "Raw mode" port setting puts the redirected port in raw mode: no
configuration or status information is sent between the PC and the server.

Resolved Problems 
================= 
o Non-admin users under Windows 2000 could not use the redirector
because of registry access violations.

Known Problems
==============
The maximum number of comports that can be successfully redirected using
Windows 98 is 33 and the maximum number that can be redirected using 
Windows ME is 62.  Windows NT and Windows 2K will correctly redirect 64
com ports.

Timeout reconnect does not work in listen mode under Windows 95/98.

Applications that open a comm port more than once will not work.  This 
includes packages such as Procomm that have separate data and fax 
channels.  See the application notes below.

Certain modems profiles will disconnect the redirector session when
the modem init string is sent.  If you notice that the redirector
connects and then disconnects right away then use the Modem Control
Panel to change your modem profile to one of the Standard modem types.
This tells Windows to send a generic init string which does not
override the LRS init string.

Faxing works with fax class 2 only and the modems noted below.

Requirements
============
The following things are required to run the redirector:

1. A Lantronix LRS running firmware version B1.3/302 or higher or a
   Lantronix terminal server or MSS running B3.5/901 or higher.

   LRS (& ETS)
   -----------
   Follow the directions in the reference manual for adding a
   dial-out service to the LRS.  For redirection over IP, be sure to use
   the TCPPORT option to specify a socket number for the service.  This
   will be in the 4xxx range.

   MSS
   ---
   For redirection over IP to a MSS the serial port is always 3001,
   and over IPX the serial port name is MSS_xxxxxx_S1 where xxxxxx
   is the last 6 characters of the unit's ethernet address in hexadecimal.

   ETS
   ---
   Redirection to a terminal server will also work to port 30xx, where
   xx is the serial port number.  For instance 3005 will establish a
   redirector connection to serial port 5 on an ETS.

2. A PC running Windows 95, Windows 98, Windows NT 3.51 or NT 4.0
   running on an IP and/or IPX network.  The IP and/or IPX stacks need
   to be configured properly.


Windows 95 Application Notes
============================
The following packages have been tested against the Windows 95 redirector:

32-bit applications
-------------------
o FedEx Ship 2.1
  Connects to the service, dials the modem, then locks up.

o Netmanage ChameleonNFS Client 5.0
  This program replaces Microsoft's wsock32.dll with a version that
  doesn't support IPX/SPX.  If this client is installed on your PC the
  redirector will not work with IPX.  You must use IP.

o Compuserve 3.0.1 for Windows 95
  Has problems.  Maybe conflicts with ethernet IP stack and/or Winsock?

o pcAnywhere32
  Works

o Windows 95 Dial-Up Networking
  Works.

o HyperTerminal (comes with Windows 95)
  Works

o Microsoft Fax (see modem chart below)
  Requires fax class 2:

  Find out if you modem supports fax class 2:
  - AT+FCLASS=? will give you a comma-separated list of supported
    fax classes, like 0,1,2
  - The '2' indicated fax class 2.
  - 2.0 is not the same as fax class 2.  If your modem doesn't
    support fax class 2 then it won't work with the redirector.

  Change your fax modem to use Class 2 fax:
    1. Control Panel -> Mail and Fax
    2. Select Microsoft Fax
    3. Properties -> Modem
    4. Select the modem associated with the redirected port 
    5. Properties -> Advanced
    6. Check "Use Class 2 if available"

o Delrina Winfax Pro 8.0 for Windows 95 (see modem chart below)
  Need to use TAPI and fax class 2:
    1. Within the application go to Setup -> Modems.
    2. Select the modem and go to Properties.
    3. Set the Communications port to TAPI
    4. Set the Fax/modem type to Class 2

o Qmodem Pro for Windows 95
  Works

o Reachout 6.0 for Windows 95
  Have to enable TAPI option.  Unstable connecting and disconnecting
  due to port cycling.  Seems to work better with only one service in
  the redirected services list.

o Reachout 7.0 for Windows 95
  Works, but has same connect/disconnect cycling problem as 6.0
  version, so not always reliable.

o HotFax MessageCenter for Windows 95
  Sending faxes works.  Data terminal works.

16-bit applications
-------------------
o 16-bit Windows terminal
  Go to Settings->Communications and set Flow Control to Hardware.
  Go to Settings->Modem Commands and delete the Originate string.  (The
  LRS correctly initializes the modem)

o Trio DataFAX Lite 4.1
  Wouldn't install under Windows 95.

o CompuServe WinCIM 2.0.1
  Works

o America Online 3.0
  Works

o SoftNet FaxWorks 3.0
  Couldn't get it to recognize a non-local modem.

o ComIt Lite for Windows 1.17
  Wouldn't install under Windows 95.

o Reachout 5.0
  Doesn't wait for an "OK" response from the modem between the init
  string and the dial string.  Modem won't dial.

o Reachout 6.0 for DOS/Windows
  Works, but this package has other problems not related to the
  redirector.  Have to check the telephony option.

o HyperACCESS Lite (similar to HyperTerminal, also by Hillgraeve)
  Haven't tested yet.

o Hayes Smartcom for Windows 1.1A
  Works fairly well.

o Hayes Smartcom for Windows LE 1.0B
  Connects and then immediately disconnects.

o Procomm Plus 2.1 for Windows
  Data connection will work, but can't have both data and fax
  connections.  Fax connection must be set to "None."

DOS Applications
----------------
The redirector can be used with DOS applications under Windows 95 by
using TurboCom VIP from Pacific CommWare.  This package intercepts all
COM port traffic from DOS and sends it to the redirector.  Currently
the only DOS apps that have been tested in this manner are Kermit and
Procomm Plus for DOS, but other applications should work.

Windows NT Application Notes
============================
The following packages have been tested against the Windows NT redirector:

32-bit applications
-------------------
o HyperTerminal for NT 4.0
  Works.

o Dialup Networking for NT 4.0
  Works.

o pcAnywhere32
  Works.

o Reachout 7.0 for NT (4.0)
  Works, but a little spastic connecting and reconnecting.

o Terminal for NT 3.51

o Delrina WinFax Pro 8.0 for Windows 95/Windows NT
  When you try to send a fax it will pop up a box which says, "Unable to
  communicate with modem."  If you click on "Retry" it will work correctly.




Fax modem table
===============
The following fax modems have been tested against the redirector and
Delrina WinFax PRO 8.0 and Microsoft Fax for Windows 95:

*1 You must delete the &c1 from the Delrina's modem init string for this modem.
*2 At the end of the fax transmition Delrina reports a "cannot send data
   to hardware" message even though the fax was sent successfully.
*3 These are apparently Australian modems that are reported by users to
   work.  They have not been tested in-house.
*4 It's been reported that Boca no longer supports fax class 2 in any of
   their modems, so don't expect faxing to work if you buy a new one.
*5 This has been reported in from the field as "working great" but has
   not been tested first-hand.  Caveat emptor.
