-
- This version of the file COMMPAK2.DLL is a replacement for the file
- of the same name which is distributed with the Oberon Terminal
- Emulator/2. The dynalink library contains the routines which TE/2
- uses for its low and medium level access to the communication device,
- terminal emulation, and file transfer protocols.
-
- If you are currently using TE/2 version 1.20 you should replace
- your existing COMMPAK2.DLL with this file.
-
- This version of COMMPAK2.DLL is NOT guaranteed to work with any
- version of TE/2 prior to version 1.20. If you are using a version
- of TE/2 prior to 1.20, you should obtain the latest version.
- Please contact Oberon Software if you are unable to locate a copy.
-
- Oberon Software will no longer officially support versions of TE/2
- prior to Version 1.10.C nor versions of COMMPAK2.DLL prior to Version
- 0.99.
-
- -------------------------------------------------------------
-
- The CommPak/2 Dynamic Link Library is a shareware product of
- Oberon Software. You may freely use it in conjunction with TE/2 with
- no further registration commitment than is already implied by your
- use of TE/2. If you are already a registered user of TE/2, use of
- this file is completely free. If you have not registered TE/2, you
- are urged to do so, but this file is considered to be part of the
- shareware package and does not require its own separate registration.
-
- Enhancements to this library will occur from time to time
- independent of version releases of other Oberon Software products.
- The most current version of this library, so long as it is compatible
- with the current released version of TE/2, will always be available
- on the Oberon User Support BBS (507/388-1154, HST). We will also
- make sure that new releases of this library appear on GEnie,
- Compuserve, BIX, and major BBSes around the world as they become
- available.
-
-
- -------------------------------------------------------------
-
- INSTALLATION:
-
- If you have already installed a compatible version of TE/2 (as
- defined above), simply locate the file COMMPAK2.DLL on your hard disk
- and replace it with this copy of that file. Please note that if TE/2
- is currently running you must exit TE/2 before copying the new file
- over the existing one. The next time you start TE/2 the new dynamic
- link library will be used.
-
- If you have not yet installed TE/2, please follow the installation
- instructions contained in the TE/2 documentation and then replace
- COMMPAK2.DLL as outlined in the previous paragraph.

- WHAT'S NEW?
-
- File Transfer Protocols
- =======================
-
- All file transfer protocols have been reworked somewhat. YModem
- has been recompiled to remove some overzealous compiler
- optimizations which were causing troubles in many cases. A
- "priority contention" between several threads (used in all the
- protocols) has been resolved which should result in more robustness
- for all the protocols. ZModem has been heavily worked on to deal
- with several problems including the occurrence of large numbers of
- retried packets, CRC errors, and failure to resynchronize after
- retried packets. Further, the ZModem in Commpak/2 1.00 would fail
- to work with some other implementations of ZModem such as the DOS
- program DSZ and the Unix sz if the sending program attempted to
- escape control characters. This problem has been addressed. This
- implementation of ZModem will NOT work with the complementary rz/sz
- which Omen Technologies distributes for VAX VMS systems because
- those programs contain copyrighted ZModem-90(tm) extensions which
- insure that these programs will only operate in conjunction with
- other Omen products. Omen Technologies sells a VAX VMS version of
- rz/sz which will work with other vendors ZModems. If you need
- this, you must contact Omen.
-
-
- General notes on the COMMPAK2FLAGS environment variable
- =======================================================
-
- The two items below both instruct you to set or unset some flags in
- this environment variable. It would seem to be a good idea to
- restate the format for this here before proceeding. The variable
- must be set in the OS/2 environment before TE/2 is executed;
- Commpak/2 reads the value only at start-up. Thus, you should set
- the value in your config.sys file or, if you start TE/2 from a
- batch file, you could set it there. The general format of the
- variable is:
-
- set COMMPAK2FLAGS=<flag1>:<val1>;<flag2>:<val2>; ...
-
- where "flag1" and "flag2" are one-letter settings, "val1" and
- "val2" are the values to which the flags are set and their format
- depends on the flag in question. You may have as many or as few
- flags in this list as you need, each flag/value pair is separated
- from the next by a semicolon. The list itself should be
- terminated with a semicolon.
-
- Thus, to set the VT100 default attribute flag (discussed below) to
- "23" and the Extended Hardware Buffering flag (also discussed below)
- to "N", you would use the following statement in your config.sys or
- start-up batch file:
-
- set COMMPAK2FLAGS=V:23;X:N;
-
- Currently, the available flags are:
-
- Flag Value
- ---- -----
- 'K' Set to 0, 1, or 2 will determine how (or whether) the file
- transfer protocols sample the keyboard for the ESCape key.
- 0 implies no keyboard check, 1 will cause it to use a
- no-wait keyboard read, and 2 will use KbdPeek to check for
- a keystroke. Default value is 2.
- 'V' Set to a number from -1 to 255 to set the VT100 default
- screen attribute. -1 (the default) will enable the default
- VT100 screen attribute of white on black (7). See
- discussion below.
- 'X' Set to 'Y' or 'N'. Default is 'N'. If set to 'Y', this
- will cause the file transfer protocols to attempt to enable
- the device driver's Auto-Buffering mode for the 16550 UART.
- Otherwise, the setting will be left as is. See the
- discussion below.
-
-
- VT100
- =====
-
- People have suggested that it would be more esthetically pleasing
- if there were a way to override the VT100 default color attribute
- of White on Black to a setting of the user's choice. As an interim
- measure, you are now able to set this via the COMMPAK2FLAGS
- environment variable. To do this set the flag "V" to the decimal
- value of the attribute you would like the VT100 to use as the
- default (note, to make this work the best, this should be the same
- value you use for the TermAttr in TE2.INI).
-
- For example, if you like white text on a blue background you should
- set TermAttr to 23 in TE2.INI and your COMMPAK2FLAGS setting should
- contain "V:23;" (in TE2.INI you have the option of using the hex
- notation: 0x17). There is a table in the TE/2 documentation which
- should help you in deciding what the numeric value of the color
- attribute you wish to use is. In the next release of TE/2, this
- will be directly settable from TE/2; the COMMPAK2FLAGS flag is only
- an interim workaround.
-
-
- Extended Hardware Buffering
- ===========================
-
- Changed default value on "X" flag for COMMPAK2FLAGS:
- ----------------------------------------------------
- The "X" flag (which is set to "Y" or "N" to enable/disable the
- probe for a 16550 UART when protocols start up) used to default to
- "Y", it now defaults to "N" because the OS/2 com driver mishandles
- this on some machines (notably some PS/2 model 70's with a 16450
- UART in which case it causes OS/2 to halt!). Thus, if you have
- been instructed to "set COMMPAK2FLAGS=X:N;", you can now remove
- this from your config.sys or session start-up if you would like.
-
- General note regarding Extended Hardware Buffering
- --------------------------------------------------
- It is probably best to set this via the OS/2 MODE command as is
- appropriate for your hardware and to set TE/2 and Commpak/2 to not
- alter the setting. With the change in COMMPAK2FLAGS mentioned
- above, no further action is required for Commpak/2. For TE/2, you
- should make sure that the keyword "ExtendedFIFO" is either deleted
- or "commented out" of your TE2.INI file and/or modem include file.
-
-
- -------------------------------------------------------------
-
- We intend to document the API (Application Program Interface) for
- CommPak/2 and make it available to interested parties. If you are
- interested in such a toolkit, fell free to contact Oberon Software
- via the Oberon BBS for information.
