-
- Remote Debugging with CodeView
- ------------------------------
-
- The required files needed on the host and the remote debugging
- machine are operating-system dependent.
-
- For running CodeView under MS-DOS, the following files must be
- installed on the MS-DOS host. These files are needed for all
- execution models:
-
- - CV.EXE (CodeView kernel)
- - SHD1.DLL (symbol handler)
- - EED1CXX.DLL or EED1CAN.DLL (C++ expression evaluator or ANSI C
- expression evaluator. Only one is needed, but EED1CXX.DLL
- is required for programming with C++. EED1CXX.DLL is the only
- expression evaluator provided with MASM.)
-
- For remote debugging, you need to include these statements in the
- [RCVCOM] section of your TOOLS.INI file:
-
- parameters: com1:9600
-
- or specify this at the command line:
-
- RCVCOM [-p com1:4800] [-r] [-?]
-
- where [ ] represents an optional parameter. See page 370 in the
- "Environment and Tools" manual for a description of these parameters.
-
- Remote debugging has three limitations:
-
- - You must specify that the shell be exclusive.
-
- - The recommended baud rate is 9600. If you experience any problems,
- try decreasing the baud rate.
-
- - The shell should be specified as full screen.
-
- Specify these settings in a .PIF file or in an MS-DOS session. Use the
- Settings command to specify these settings in an MS-DOS shell.
-
- If you install a CodeView DLL in a directory other than where Setup
- installs it, specify the path of the DLL with the appropriate entry
- in your TOOLS.INI file. For example:
-
- SYMBOLHANDLER:C:\CV4\SHD1.DLL
-
- See also "Configuring CodeView with TOOLS.INI" on page 301, and
- "Remote Debugging" on page 367, both in the "Environment and Tools"
- manual.
-
- The following four sections describe additional files you need for
- specific hosts and targets.
-
-
- DOS-Hosted, DOS-Targeted Debugging: Host Computer
- -------------------------------------------------
-
- If you are not doing remote debugging, these additional files
- must be installed on the host computer for DOS-hosted,
- DOS-targeted debugging:
-
- - EMD1D1.DLL (DOS host/DOS target execution model)
- - TLD1LOC.DLL (local transport layer)
-
- If you are doing remote debugging, these additional files must
- be installed on the host computer for DOS-hosted, DOS-targeted
- debugging:
-
- - EMD1D1.DLL (DOS host/DOS target execution model)
- - TLD1COM.DLL (COM port transport layer)
-
- To specify these transport options, use the TRANSPORT statement
- in your TOOLS.INI file. The path must be specified:
-
- TRANSPORT:C:\CV4\DLL\TLD1COM.DLL COM1:9600
-
- If you do not specify COM#:baud_rate in the TRANSPORT statement,
- CodeView prompts you for it.
-
- You must also add the Native entry to your TOOLS.INI file giving
- the execution model. The path is required:
-
- NATIVE:C:\CV4\EMD1D1.DLL (for DOS host/DOS target execution model)
-
-
- DOS-Hosted, DOS-Targeted Debugging: Target Computer
- ---------------------------------------------------
-
- If you are doing remote debugging, this file must be installed
- on the target computer for DOS-hosted, DOS-targeted debugging:
-
- - RCVCOM.EXE (remote CodeView for COM port)
-
-
- DOS-Hosted, Windows-Targeted Debugging: Host Computer
- -----------------------------------------------------
-
- If you are doing remote debugging, these additional files must be
- installed on the host computer for DOS-hosted, Windows-targeted
- debugging:
-
- - EMD1W0.DLL (DOS host/Windows target execution model)
- - TLD1COM.DLL (COM port transport layer)
-
-
- DOS-Hosted, Windows-Targeted Debugging: Target Computer
- -------------------------------------------------------
-
- If you are doing remote debugging, these additional files must be
- installed on the target computer for DOS-hosted, Windows-targeted
- debugging:
-
- - RCVWCOM.EXE (remote CodeView for COM port)
- - DMW0.EXE (debug monitor on Windows target)
- - TOOLHELP.DLL (Toolhelp)
-
-
- Debugging Locally on an 80286
- -----------------------------
-
- To run CodeView with Windows and debug locally on an 80286 computer,
- these files must be installed on the host computer:
-
- - CVW4.EXE (CodeView kernel)
- - EEW0CXX.DLL (C++ expression evaluator)
- - EEW0CAN.DLL (ANSI C expression evaluator)
- - SHW0.DLL (symbol handler)
- - EMW0W0.DLL (Windows-Windows execution model)
- - TLW0LOC.DLL (local transport layer)
- - TOOLHELP.DLL (Toolhelp)
-
-
- Running CodeView on an 80286 Computer
- -------------------------------------
-
- To run CVW on an 80286 computer, delete CVW.EXE and rename CVW4.EXE as
- CVW.EXE. Local debugging on an 80286 computer with an EGA adapter
- requires a secondary monitor. Single-screen debugging is not supported.
- Local debugging on an EGA requires CodeView to be invoked with the /2
- command-line option.
-
-
- Debugging Code Which Uses 32-Bit Registers
- ------------------------------------------
-
- CodeView does not support single-stepping through code which uses
- the 32-bit registers of the 80386 and higher CPUs, if a DPMI server
- is present. Windows 3.1 and 386-MAX are examples of DPMI servers.
- In order to single-step through 32-bit code, you must exit Windows or
- disable your DPMI server and use a VCPI server such as EMM386.EXE to
- run CodeView. Alternately, you can use a different debugger such as
- WDEB386 (available in the Microsoft Windows Software Development Kit).
-
-
- CodeView's Access to Function Code in Libraries
- -----------------------------------------------
-
- The MASM CodeView debugger and linker do not guarantee that the
- name of an .OBJ file is the same name the debugger or linker uses
- to access the function code. To be certain of function access, use
- the /f option when compiling. To avoid problems, do not put code in
- include files. If you do put code into include files, specify the
- function as inline.
-
-
- Unloading DLLs When CodeView Terminates
- ---------------------------------------
-
- You may have applications that use the LoadLibrary function to load
- DLLs to be used by the application. When CVW.EXE terminates or
- restarts such applications, Windows terminates the application without
- unloading DLLs or decrementing the DLL usage count. As a result, DLLs
- still exist in the system. To unload DLLs, you must either exit
- Windows and restart, or use a utility.
-
-
- Removing CodeView 3.07 from SDK Program Manager Group
- -----------------------------------------------------
-
- You can safely remove CodeView 3.07 from your SDK Program Manager
- group to avoid confusion with the CodeView for Windows provided
- with MASM or MS C/C++.
-
-
- Unsuccessful Connection to Remote Terminal
- ------------------------------------------
-
- A remote monitor may appear to hang (the screen clears except for
- the CodeView sign-on banner) when connecting to it from a host that
- is running the debug kernel. In order to resolve this situation,
- retry the connection when the debug kernel is not running on the
- host computer.
-
-
- Running Screen Saver Programs While Debugging
- ---------------------------------------------
-
- Do not run screen savers such as Idlewild or AfterDark while
- debugging, as their interactions with Windows can cause problems
- when debugging.
-
-
- MS-DOS Session Running in a Window Does Not Have Mouse Support
- -----------------------------------------------------------
-
- Running CodeView with the /2 option in an MS-DOS session window does
- not have mouse support. If you want mouse support, change the
- DOS session to full screen.
-
-
- Application I/O When Debugging Can Cause Screen Corruption
- ----------------------------------------------------------
-
- If an application executes an I/O operation when the Flip/Swap
- option is OFF, the screen may be corrupted.
-
-
- Recovering From "Internal Debugger Error"
- -----------------------------------------
-
- If CodeView generates an "Internal debugger error," restart your
- system.
-
-
- Debugging Applications That Use a Mouse
- ---------------------------------------
-
- If you are using CV.EXE in a Windows MS-DOS session, and if you are
- debugging an application that uses or alters the mouse, you must
- specify the CodeView /M option to disable the mouse. This option is
- necessary because the DPMI services provided by Windows 3.x in
- enhanced mode do not allow for saving and restoring the mouse state
- correctly.
-
-
- Setting the Scope of the Show Address Option in CodeView
- --------------------------------------------------------
-
- The printed documentation and Help incorrectly list the
- syntax for setting the scope of the Show Address option in
- the CodeView Command window (OL) as:
-
- OL[<scope>]
-
- instead of:
-
- OL[[<scope>][+|-]].
-
- The + and - switches can be used to turn other options on or
- off, but will cause a syntax error if used to modify the scope
- of the Show Address option.
-
- Several options for the OL command can be chosen at the same time.
- Each time you use the OL command, the scopes you specify will be
- turned on and the scopes you don't specify will be turned off.
- The OL command does not toggle the scopes. For example, the command:
-
- ollfg
-
- turns on lexical, function, and global scope while it turns off module
- and executable scope.
-
-
- Disable the Minimize On Use Option When Debugging
- -------------------------------------------------
-
- Running an application in CodeView for Windows can disable
- mouse and keyboard control if the Minimize On Use option
- is set in the Windows Program Manager. This behavior occurs
- if you run an application using F5, restart from the Run
- menu, and begin to debug the application. If you experience
- this problem, use CTRL+ALT+SysRq to stop the application,
- issue the WKA command from within Codeview for Windows, and
- choose Exit from the File menu to return to Windows.
