1994 Updates
----------+------------------------------------------------------------------
Date | Change(s)
----------+------------------------------------------------------------------
01/01/94 | This log started.
----------+------------------------------------------------------------------
01/04/94 | ATB/Windows: CFXDIALG.OBJ/DIALOGG.EXE/CFXATB?D.DLL
| Day of week checked in CLOCK statement only if day of week
| actually specified (corrected in CFXDIAL 5/12/92).
----------+------------------------------------------------------------------
01/05/94 | ATB/Windows: WTBENCH.C/.EXE
| WTBENCH was not doing a LocalUnlock in all cases when the
| StartDialog command was issued. Was causing a FatalExit
| code when running under the debug kernel.
----------+------------------------------------------------------------------
02/09/94 | DOS CFXHLLX: If HLLAPI trace turned on and HLLAPI not
| loaded, machine lockup occurred as the result of
| attempting to do API call to trace HLLAPI system
| info. Unloaded interrupt vector caused the lockup.
----------+------------------------------------------------------------------
02/15/94 | DOS CFXHLLX: Add reasonability test and correction for
| returned cursor position. This is a workaround for a
| bug in DCA's pocket adapter HLLAPI version 1.0.1.
----------+------------------------------------------------------------------
03/02/94 | HLLXTRAC.EXE extended to support structure field trace entries.
----------+------------------------------------------------------------------
03/10/94 | ATB/Windows: WTBENCH.C/.EXE
| A bug (that was bypassed due to a compiler quirk) in
| XAPIcommand() was corrected.
----------+------------------------------------------------------------------
03/22/94 | APPX: When using Text-Translate tables, PC APPX's with gen dates
| of 10/21/93 and 11/09/93 sometimes forced the use of a
| standard U.S. English translate table, making it impossible
| to load a specific text-translate table. Also corrected
| is the reporting of the Text-Translate table in use in
| the statistics blocks and in the APPX trace - formerly APPX
| traced the value configured in MAINCON, rather than the value
| actually used.
|
| MAINXLAT:
| MAINXLAT could crash with a runtime "subscript out of bounds"
| error on some text-translate files with 0xff specified as
| a translation.
----------+------------------------------------------------------------------
03/29/94 | ATB/Windows: CFXDIALG.OBJ/DIALOGG.EXE/CFXATB?D.DLL
| In certain cases, if the 3270 model changed, CFXDIALG was
| not adjusting and returning an "032: Invalid buffer position"
| error. The 3270 model changes when the host issues an
| Erase-Write while in alternate mode, or an Erase-Write-Alternate
| while in basic mode, and only if the 3270 is operating in
| model 3, 4 or 5 mode. This was usually manifested during
| a "WAITFOR" command.
----------+------------------------------------------------------------------
04/22/94 | CFXDFTS.BIN & CFXDFTN.BIN (cfDFT drivers for DOS):
| Allow Clear key while in VTAM TTY (unbound) state.
| EraseInput could crash if used on an unformatted screen.
| EraseInput did not clear the MDTs.
|
| CFXDFTS only: at Bind time, the 3270 image (screen) is now
| cleared as per the 3270 definition. (Change made 10/14/93
| (beta release), moved into production this date).
----------+------------------------------------------------------------------
04/28/94 | "Purpose of Document" section revised.
----------+------------------------------------------------------------------
05/18/94 | ATB/Windows: CFXDIALG.OBJ/DIALOGG.EXE/CFXATB?D.DLL
| Bug introduced in 3/29/94 change caused failure to timeout
| in WAITFOR.
----------+------------------------------------------------------------------
05/18/94 | CFXEICO.DLL Changed DLL name to EHLLAPI.DLL from ACS3EHAP.DLL.
| The former name was causing us to pick up other vendor's DLLs
| in some cases (e.g. Irma WS for Windows, which also uses
| ACS3EHAP).
----------+------------------------------------------------------------------
06/07/94 | CFXPCOX.BIN (ATB/DOS)
| Improve version check of loaded Novell software.
----------+------------------------------------------------------------------
06/15/94 | ATB/Windows: CFXAPI
| Was passing NULL handle to GlobalLock() in some cases,
| was resulting in message when using debug kernel.
----------+------------------------------------------------------------------
06/16/94 | APPX (PC and Mainframe) - Beta v3.12 which includes HLLAPI
| structured field support. One beta HLLAPI structure field
| driver, CFXIBWS.DLL (XAPI device #55, DIALOG DEV() name
| "IBW-SF"), and an updated XAPI and DIALOG supporting this
| device are included in this beta release for Windows. PC
| applications may use this new driver transparently. Non-APPX
| host applications using structured fields will need to be
| modified to used DOIDs (see the "Using GET-SF and SEND-SF in
| XAPI" document). Note: Mainframe APPX 3.12 is the earliest
| release that supports HLLAPI structured fields. An attempt
| to use a HLLAPI-SF driver to connect to a 3.11 or earlier
| mainframe APPX will result in a timeout error on the PC, may
| result in the host application receiving an I/O error.
----------+------------------------------------------------------------------
06/23/94 | XAPI and CFXDIAL/CFXDIALG/DIALOG/DIALOGG -
| CFXPROX and CFXDECX for ATB/DOS and ATB/Windows -
| CFX220X, CFXDN22 and CFXTN?? for ATB/Windows -
| ApkClearBuf key added for XAPI apisndkey function.
| CLEARBUF DIALOG SEND keyword added for same function.
----------+------------------------------------------------------------------
07/25/94 | XAPI, APPX, CFXDIAL/CFXDIALG/CFXDIALW/DIALOG/DIALOGG for OS/2:
| The following new drivers added:
|
| CFXCMGS.DLL #61 CMG-SF OS/2 EE Comm Mgr/SF
| CFXEXTO.DLL #62 EXO Extra! for OS/2 (not SF!)
| CFXT3IO.DLL #65 TN3IBMO TN3270 IBM TCP/IP/OS2 non-SF
| CFXT3IO.DLL #66 TN3IBMO TN3270 IBM TCP/IP/OS2
| CFXT3FO.DLL #67 TN3FTPO TN3270 FTP PC/TCP/OS2 non-SF
| CFXT3FO.DLL #68 TN3FTPO TN3270 FTP/PC/TCP/OS2
| CFXT3LO.DLL #69 TN3LWPO TN3270 Novell LWP/OS2 non-SF
| CFXT3LO.DLL #70 TN3LWPO TN3270 Novell LWP/OS2
|
| Drivers 65-70 are TCP/IP TELNET TN3270 drivers similar in
| function to the Windows TCP/IP drivers. Driver 61 provides
| structured field HLLAPI support for OS/2 Communications
| Manager. Driver #62 supports Extra! for OS/2 (no SF support).
|
| Note that CFXT3IO.DLL (65/66) is beta as of this date.
|
| Updates to various utilities and sample programs to
| support these new drivers.
|
| Programming note: CFXT3IO.DLL requires more stack space
| than previous drivers. Insure that at least 8KB of stack
| space is available before calling this driver.
----------+------------------------------------------------------------------
07/28/94 | CFXT3NW.DLL: (Chameleon/Newt TN3270 driver for Windows):
| Could return "066: T3NW err 35 @ senda" in some rare cases.
| Condition is normal, and is ignored as of this date.
----------+------------------------------------------------------------------
07/29/94 | CFXATBxx.DLL: (Windows)
| Was allocating fixed storage unnecessarily.
----------+------------------------------------------------------------------
08/01/94 | CFXT3NW.DLL: (Chameleon/Newt TN3270 driver for Windows):
| Added additional case to 07/28/94 fix.
----------+------------------------------------------------------------------
08/05/94 | ATB/Windows: Visual BASIC sample programs added.
----------+------------------------------------------------------------------
08/09/94 | PCAPPXCT.EXE (ATB/Windows):
| Forced PC trace disable at APPX connect - was sometimes
| overlaying PC APPX trace while downloading the mainframe
| APPX trace.
----------+------------------------------------------------------------------
08/19/94 | TN3270 drivers (all): several errors in 3270 datastream
| processing were corrected: SNA/BSC style commands now correctly
| interpreted, the response to a Read-Buffer command now contains
| the entire buffer, the processing of a structured field following
| a 3270DS structured field no longer produces PROG909/911 errors,
| in some cases PROG401 was incorrectly produced instead of a
| PROG402.
----------+------------------------------------------------------------------
08/19/94 | CFXT3WS.DLL and CFXT2WS.DLL (Windows Sockets TCP/IP drivers):
| Was leaving WINSOCK.DLL loaded in some cases if the initial
| Get-Socket failed.
|
| CFXT2NW.DLL: 07/28/94 and 08/01/94 CFXT3NW changes ported to
| this driver.
----------+------------------------------------------------------------------
09/22/94 | ATB/Windows CFXT3WS.DLL, CFXT2WS
| Was leaving WinSock DLL loaded if GetSocket failed because
| TCP/IP stack not running.
----------+------------------------------------------------------------------
11/22/94 | ATB/Windows:
| Win32s thunk to ATB/Win16 available. XAPI support only.
| Provides the same API as ATB/Windows NT to a Win32s
| application. Usage note: review the Microsoft documentation
| on stack usage by Universal Thunks in a Win32s application.
