TITLE   : RPI Modem Setup
PRODUCT : PROCOMM PLUS for Windows 2.xx
==============================================================================

This paper describes the operation of RPIBIOS.DLC, a Dynamic Link Connection
module that allows PROCOMM PLUS to communicate with WinDAPI, the
software-based V.42/MNP .DLL written in conjunction with Rockwell
International.  This .DLL is specifically for use with modems equipped with
Rockwell RPI chip sets, such as the RC224ATF/ATL, 144ATI and all future RPI
chip sets.  Using RPIBIOS.DLC, you can make error-free connections and realize
speed gains through connections utilizing MNP-5 or V.42bis data compression.

MAKING THE CONNECTION
To create a custom PROCOMM PLUS RPIBIOS connection, follow these steps:

1. Open the Setup window and select the Data/Modem Connection group.

2. Click on Install New Modem or Connection.  From the drop-down list box,
   select your RPI-compatible modem from the list of available modems.  If
   your modem does not appear in the list, select a Hayes-compatible modem
   instead.

3. From the Select Port list box, scroll through the list until you see the
   "RCOM1 - Rockwell WinDAPI " entry.  Select the RCOM entry that lists the
   COM port used by your modem; if your modem uses COM2, select RCOM2.  Note
   that this entry will NOT appear if the RPIBIOS.DLC or the WINDAPI.DLL files
   haven't been copied to your PROCOMM PLUS home directory.

4. Click on the Setup Port button.  At this point, you can:

   > assign V.42bis negotiation.  The default is Both (During Transmit and
   Receive) and will work well under normal circumstances.

   > specify whether MNP-5 data compression will be used during MNP error
   correction.  The default is ON.  If you will be transferring compressed
   "archive" files - such as those ending in .ZIP, .ARC, .LZH, or .ARJ, be
   sure to set this option to OFF.  Using MNP -5 when transferring compressed
   files will actually take longer to finish the file transfer.

   > specify the Connection Protocol to be used.  The default, Auto Detect,
   will work well under normal circumstances.  If you know that the modem with
   which you're connecting is not an error-correcting model, select None from
   the list.

5. Click on the OK button on the WinDAPI dialog box.

6. If your RPI-based modem did not appear in the available modem list in step
   2, click on the Data Modem Commands subgroup; from there, click on the
   Advanced button.  Examine the modem initialization string - it should end
   in the characters ^M (for carriage return).  Edit the string by adding the
   string +H1 directly before the ^M.  Your modem initialization string might
   now look like this:

   AT&FE1V1Q0&C1&D2S7=60S11=60+H1^M

7. Once you've added the +H1 command, click on OK.

8. If your modem supports fax features, select the Fax Connection Setup group.
   Click on the Install New Fax Modem button.  Select your fax modem from the
   list; if it is not listed, select Generic Class 1 Fax, 2400 Data Modem.
   Also, select the actual COM port the modem uses--do not select the same
   RCOM port that was selected above.  Click on OK to exit the Modem Install
   dialog.

9. Click on OK to exit the Setup window.

10.  From the Online pull down menu, select Initialize Modem.

You've now created a RPIBIOS connection entry!  For more information about
specifying this connection as the default or adding it to one or more Dialing
Directory entries, please refer to your PROCOMM PLUS User Manual.

TROUBLESHOOTING
*  Use with other Network .DLCs:
   PROCOMM PLUS does not support concurrent use of both RPIBIOS.DLC and any
   other .DLC (PWNCSI.DLC, PNETBIOS.DLC, EBIOS.DLC, etc.)  Multiple .DLC usage
   will be addressed in a future version of PROCOMM PLUS.  It is also not
   recommended that you switch to RPIB IOS.DLC from another .DLC.

*  Immediate Disconnection and/or Loss of Initial Data:
   If you are using the PC Speaker Wave driver to play .WAV files for Windows
   system events, you may experience immediate disconnection when calling
   another computer.  The PC Speaker driver's setup dialog (available from the
   Control Panel Drivers dialog) includes the checkbox Enable Interrupts,
   which is disabled by default.  It is recommended that the Enable Interrupts
   checkbox be checked.

   Also, from the PROCOMM PLUS Setup window, select Sound and Alarm and either
   reduce your Alarm Time to 1 second or turn the Alarm Time off.
