NOVELL TECHNICAL INFORMATION DOCUMENT TITLE: MHS 1.5P, Revision D, Upgrade Patch DOCUMENT ID: TID200031 DOCUMENT REVISION: B DATE: 14FEB94 ALERT STATUS: Yellow INFORMATION TYPE: Symptom Solution README FOR: MHS183.EXE NOVELL PRODUCT and VERSION: NetWare MHS 1.5 ABSTRACT: This file contains the upgrade to Revision D for the Personal Edition of MHS 1.5. Make sure that you read the entire README.TXT before applying this patch. ────────────────────────────────────────────────────────────────────────────── DISCLAIMER THE ORIGIN OF THIS INFORMATION MAY BE INTERNAL OR EXTERNAL TO NOVELL. NOVELL MAKES EVERY EFFORT WITHIN ITS MEANS TO VERIFY THIS INFORMATION. HOWEVER, THE INFORMATION PROVIDED IN THIS DOCUMENT IS FOR YOUR INFORMATION ONLY. NOVELL MAKES NO EXPLICIT OR IMPLIED CLAIMS TO THE VALIDITY OF THIS INFORMATION. ────────────────────────────────────────────────────────────────────────────── ADDITIONAL CONFIGURATION Third-Party Product and Version: This revision of NetWare MHS 1.5 includes public hub support. It allows users of MHS-compatible applications to communicate with each other through third-party hub services such as the CompuServe MHS Service. Other: If you need information about the Novell mail hub (NHUB) or about registering your workgroup, call the Messaging Hotline at the following number: (408) 473-8989 To register your workgroup, you can send an MHS mail message to hubadmin@NHUB. In the message, include your workgroup name, your contact phone number, and the name of the contact person in your organization. ADDITIONAL CONFIGURATION Other: User Interface Information -------------------------- The following information applies to the user interface in NetWare MHS 1.5: SYMPTOM Monochrome Monitor Problems. The MHS screens may be difficult or impossible to read on certain VGA monochrome monitors. SOLUTION If you experience this problem, use the following MODE command at the DOS prompt before running MHS: MODE=bw80 SYMPTOM Color Monitor Problems. SOLUTION If the colors on an application display incorrectly after you run MHS, use the following MODE command at the DOS prompt before running your application: MODE=co80 SYMPTOM Null Username CAUSE The Directory Manager treats "" (null; a username with no characters) as a valid username. SOLUTION Check to make sure you have specified a username before you add a new user. ADDITIONAL CONFIGURATION Other: Communications Information -------------------------- The following information applies to communications between hosts running NetWare MHS 1.5. SYMPTOM Modem Speed Sensing. The superseded modem drivers for the Hayes V-Series ULTRA 9600 modem (96V32 and 96V32HUB) do not sense speed. As a result, they are unable to answer an incoming call at 1200 or 2400 baud. SOLUTION If you want speed sensing, use the HULTRA modem driver. SYMPTOM 9600 Baud Modem Support. Machines with 8088 processors running at the 4.77 MHz clock speed are not fast enough to use 9600-baud modems. SOLUTION Apply the MHS183.EXE file. SYMPTOM Inaccurate Estimated Transfer Time. MHS attempts to estimate the amount of time an asynchronous transfer will take. It often estimates incorrectly, especially for high-speed modems. SOLUTION Apply the MHS183.EXE file. ADDITIONAL CONFIGURATION Other: Disk Space and Memory Requirements ---------------------------------- Disk space and memory requirements for NetWare MHS 1.5 have changed, as follows: SYMPTOM Statistics Gathering. Because NetWare MHS 1.5 gathers statistics more comprehensively, statistics files require more disk space. Monitor disk space usage carefully. SOLUTION Apply the MHS183.EXE file. SYMPTOM Memory Allocation Error. If the NetWare MHS workstation has a limited amount of available memory, and a large number of files accumulate in the SND directory, a memory allocation error occurs. SOLUTION Delete any *.BAD files in the SND directory, and if possible, terminate memory-resident programs sharing the MHS workstation. Do not run MHS from a shell. SYMPTOM Disk Space Management. If MHS terminates abnormally, it might be unable to remove temporary files created in the <mv>\MHS\SW subdirectory. SOLUTION Check this subdirectory from time to time, and delete all files except SWAP.FLG. Note: Do not delete these files while MHS is running. ADDITIONAL CONFIGURATION Other: Other Information ----------------- The following information applies to NetWare MHS 1.5: SYMPTOM Invalid Remote Host Name. MHSUSER does not prevent you from adding an invalid remote host name (for example, a name containing invalid characters) to the Routing Directory. SOLUTION To avoid confusion and routing problems, delete invalid host names. ADDITIONAL CONFIGURATION Other: DOCUMENTATION CORRECTIONS ------------------------- This section provides updates and corrections to the NetWare MHS Installation and Operation guide. Passwords for Asynchronously-Connected Hosts -------------------------------------------- SYMPTOM The NetWare Installation and Operation guide incorrectly describes how to define passwords for hosts with which you communicate asynchronously. SOLUTION You can define a Password for access to hubs in the MHS HOST SETUP form. This is the password that the local host transmits when it communicates with a remote host. (It transmits the same password to all the remote hosts with which it communicates.) For each remote host the local host calls and for each remote host that calls the local host, you can define a Password (in the A HOST THAT THIS HOST PHONES and the A HOST THAT PHONES THIS HOST forms, respectively). This Password must match the password defined in the Password for access to hubs field in the remote host's HOST SETUP form. If you do not define the remote host's password at your local host, MHS will take the password transmitted by the remote host in the next communication session, and write it in the Password field of the A HOST THAT THIS HOST PHONES or the A HOST THAT PHONES THIS HOST form. After a password has been assigned to a remote host, the remote host administrator must notify you of changes to the password. When the remote administrator changes the password in the Password for access to hubs field, the local administrator must change the Password field in the A HOST THAT THIS HOST PHONES or the A HOST THAT PHONES THIS HOST form for the remote host. Otherwise, if Require Password is set to "Yes," a password mismatch will occur, and the hosts will be unable to establish a communication session. Similarly, when you change the password in the Password for access to hubs field, you must ask the administrator of the remote host to update the Password in the form for your host. To understand how passwords work, consider "Eng," a host that calls another host named "Sales." Sales has chosen "salpas" as its Password for access to hubs, and Eng has chosen "engpas" as its Password for access to hubs. These passwords are defined in the HOST SETUP form. The administrators at Sales and Eng can get together and coordinate passwords. Sales' administrator enters "engpas" in the Password field of the A HOST THAT THIS HOST PHONES form that defines the route to Eng. And Eng's administrator enters "salpas" in the Password field of the A HOST THAT PHONES THIS HOST form that defines the route to Sales. Both administrators can also set Require Password to "Yes." One or both administrators can choose not to define the password for the other host. If they leave the Password for the remote host blank, MHS will insert the password it receives during the next communication session. During this session, Eng's host transmits its password. Sales' host enters the password received from Eng in its routing table, and sends its password to Eng's host. Eng's MHS enters the Sales password in its routing table, and continues the transmission. From now on, if either administrator changes their host's Password for access to hubs, he must ask the other administrator to change the Password field in the A HOST THAT THIS HOST PHONES or A HOST THAT PHONES THIS HOST form for the remote host. ADDITIONAL CONFIGURATION Other: 96V32 and 96V32HUB Modem Driver ------------------------------- SYMPTOM The 96V32 and 96V32HUB are not drivers for the Hayes Smartmodem, as stated in the NetWare MHS Installation and Operation guide. SOLUTION The 96V32 and 96V32HUB drivers are drivers for the Hayes V-series ULTRA modem. ADDITIONAL CONFIGURATION Other: Miscellaneous MHS SYMPTOM When MHS messages are upgraded from SMF-64 to SMF-70, MHS might reject the message indicating "Bad Expiry Date Header." This problem occurred every 256 days; the last known date on which it occurred was January 7, 1992. SOLUTION Apply the MHS183.EXE file. SYMPTOM MHS would fail when it connected to the CompuServe Mail Hub from outside the United States, if the connection was made through a data network that uses 7-bit data. SOLUTION Apply the MHS183.EXE file. SYMPTOM Although it was using the "DISABLED" modem driver, MHS would still require the selected COM port to be present and would alter the settings of that COM port. SOLUTION Apply the MHS183.EXE file. With this file applied MHS no longer accesses the COM port when using the "DISABLED" modem driver. SYMPTOM Under some circumstances, the MHS workstation would hang if activity occurred on the COM PORT while a gateway was running. SOLUTION Apply the MHS183.EXE file. SYMPTOM Sometimes during message queue transfers, the warning message "Dangerous stuff" would appear. SOLUTION The condition causing this problem has been eliminated when you apply the MHS183.EXE. SYMPTOM Disk write errors that occur during INET message deliveries are no longer considered fatal errors. MHS will now count that as 1 failed connection attempt and continue processing. SOLUTION Apply the MHS183.EXE file. SYMPTOM On faster machines, the Connectivity Manager would sometimes terminate with a fatal runtime (division by zero) error. SOLUTION Apply the MHS183.EXE file. SYMPTOM Mhsuser - Option -X01 - When defining a new user of an application, mhsuser would allow you to add users if you provided an undefined application. SOLUTION Apply MHS183.EXE. With this file applied MHSUSER will no longer allow you to define a user to an undefined application. SYMPTOM MHSUSER - Option -X31 - The switch -NS for adding / modifying information for the CompuServe host's configuration would only work for the initial creation of the Cserve host. SOLUTION Apply MHS183.EXE. With this file applied MHSUSER now lets you add and modify the information for the CompuServe host. SOLUTION Self-Extracting File Name: MHS183.EXE Revision: B Files Included Size Date Time \ MHS183.TXT (This File) EXE.EXE 257810 08-03-93 10:25a SYS.EXE 370145 08-03-93 10:25a NOTE.TXT 22679 07-30-93 5:10p UPGRADE.EXE 22935 08-03-93 10:25a Installation Instructions: SYSTEM REQUIREMENTS ------------------- The NetWare MHS 1.5 Revision D (Personal edition) upgrade requires the following hardware and software: A DOS workstation running NetWare MHS 1.5P, revision A or revision B. If this copy of the Personal edition will be using an asynchronous connection on the client workstation, it also requires the following: ■ An available serial communications port (COM1, COM2, COM3, or COM4) ■ A modem from the list of modems in the section "Communication Enhancements and Improvements." ■ CompuServe User-ID and Password for each host that will be connecting to CompuServe UPGRADING YOUR HOST ------------------- The following sections describe the steps you must perform before and after upgrading your host from an earlier revision of NetWare MHS 1.5. Before Upgrading Your Host -------------------------- 1. Stop Mail Processes. Stop all mail processes (Connectivity Manager, secondary Transport Servers and applications). If you have mail pending for other hosts, force that mail to be delivered before upgrading your host. 2. Rebuild Queues. Rebuild all existing queue files to ensure they are in the correct format. Use the Rebuild all queues option from the MHS Utilities menu. 3. Back up the existing SYS, MAIL and EXE subdirectories before proceeding with the upgrade. Upgrading Your Host ------------------- To upgrade your host, use the following instructions: 1. Set the MV environment parameter to point to the path containing the MHS subdirectory. For example, if NetWare MHS is installed in d:\EMAIL, enter the command "SET MV=d:\EMAIL". 2. Run UPGRADE. The UPGRADE program warns you to back up the SYS and EXE subdirectories, and displays the path constructed from the MV environment parameter. It prompts, Is it OK to continue (Y/N): 3. If you have performed the backup and if the target directory is correct, type "Y" and press <Enter>; otherwise, type "N" and press <Enter>. If you entered "Y" in response to the previous prompt, the program upgrades your NetWare MHS installation. 4. If you plan to connect to the CompuServe Mail hub, print MANUAL.DOC, located in the <mv>\MHS\SYS directory, and follow the instructions in that document. It will tell you how to configure the CompuServe Mail Hub and register your workgroups and hosts with CompuServe. 5. Run the Directory Manager at least once after upgrading your host. The Directory Manager automatically updates the MHS version number and serial number in the Routing Directory (NETDIR.TAB). Solution Specifics: FEATURES OF NETWARE MHS 1.5, REVISION D --------------------------------------- NetWare MHS 1.5P, revision D, incorporates the following new and revised features. Communication Enhancements and Improvements ------------------------------------------- NetWare MHS 1.5 includes the following enhancements and improvements for communication between hosts: Connection to CompuServe. Through NetWare MHS 1.5, revision D, you can use the CompuServe Mail Hub to route mail between NetWare MHS workgroups, members of the CompuServe Information Service, and other users of CompuServe Mail. Session Recovery. The Connectivity Manager resumes transmissions where it left off when a broken transmission restarts. Abort and Retry Captured. When a network error occurs, the I/O operation is retried. If the retry count has been exhausted, the Connectivity Manager or gateway is restarted. The Abort/Retry counter is reset after a successful connection. Retry Counter Reset. The Retry counter now resets after a successful connection to another host. Previously, this function was disabled. Expanded Serial Port Support. NetWare MHS supports modems on serial ports COM3 and COM4. Support for 9600 Baud Modems. NetWare MHS 1.5 supports 9600 baud modems. Improved Modem Support. To support new modems with software UARTs that use only one stop bit for communication, NetWare MHS 1.5 uses only 1 stop bit. It also supports modem definitions with large command sets. Included with this release are versions of the MHS 1.5 modem drivers that handle hang-ups properly with CompuServe. If you are using any of the drivers that came with your MHS 1.5, revision A software, you must use the equivalents included with this release. Support for Additional Modem Drivers. NetWare MHS now supports the following modem drivers: 2400B For Hayes Smartmodem 2400 and Hayes-compatible modems operating at 2400 baud. Use for calling hosts only. 2400B-CE For modems bundled with the COMPAQ LTE. Try using the CMPQLTEB modem driver first. 2400B-HUB For Hayes Smartmodem 2400 and Hayes-compatible modems operating at 2400 baud. 96V32 For Hayes V-Series ULTRA 9600 modems. Use for calling hosts only. 96V32HUB For Hayes V-Series ULTRA 9600 modems. BULLET96 For E-Tech BulletModem E9696M modems without MNP. BULLETEC For E-Tech BulletModem E9696M modems with MNP.

For hosts that do not exchange messages with remote hosts through telephone calls. FAXMDM For generic SendFax-compatible modems. HAYESMAN For Hayes-compatible modems that require telephone numbers to be dialed manually. HAYES-UN For Hayes-compatible modems operating at speeds up to 2400 baud. HAYESX24 For generic Hayes-compatible 2400 baud modems. HAYESSM For Hayes Smartmodem 2400 modems. HSTD-HUB For US Robotics COURIER HST modems with MNP. HSTDNMNP For US Robotics COURIER HST modems without MNP. HULTRA For Hayes V_Series ULTRA Smartmodem 9600 modems. Replaces the 96V32 and 96V32HUB drivers. INTELFAX For the Intel SatisFAXtion board. INTELV32 For Intel 9600EX modems. MICROCOM For Microcom QX4232HS modems. MULTEC For MultiTech 932/224 modems. This driver does not alter Novram setup. MULTECNR For MultiTech 932/224 modems. This driver alters Novram setup. MULTEC20 For older MultiTech 224 modems. This driver does not alter Novram setup. NEC9631 For NEC 9631 modems. NEC9632 For NEC 9632 modems. NULLMDM For hosts with a direct cable connection between their communication ports. You can use NULLMDM as a platform for developing modem-control files. PP96-HUB For Practical Peripherals PM9600SA modems. Use for both hubs and calling hosts. UDS322X For Motorola UDS v. 3224/3225 and Codex 1133 modems. This list supersedes the one in Appendix C of the NetWare MHS Installation and Operation guide. Note: If you want to use one of these modem drivers, refer to the MODEM.DOC file in the <mv>\MHS\SYS directory for installation instructions. SMF Enhancements and Improvements --------------------------------- NetWare MHS 1.5 includes the following enhancements and improvements to the SMF standard: Support for Extended Addresses. While MHS 1.5, revision D does not use extended addresses to route messages, it now examines extended address elements in braces ({ }) when checking for duplicate addresses. For example, a message contains the following addresses: mail@fax {FAX: 1-408-555-1212} mail@fax {FAX: 1-408-555-1211} Previously, MHS would compare only the base address (mail@fax). Since the base address is the same in both instances, MHS 1.5 would only deliver one message, containing the first address, to the fax gateway. MHS 1.5, revision D recognizes the two addresses as distinct, and delivers two copies to the fax gateway. Note that MHS does not interpret the contents of the braces; it only detects that they are different. Thus, if in the previous example, the addresses were the following then MHS would send two copies: mail@fax {FAX: 1-(408)-555-1212} mail@fax {FAX: 1-408-555-1212} This change supersedes the information in the SMF v70 Programmer's Reference.
