SUMMARY
=======

The only COM port setting for the Windows 80386 Debugger (WDEB386) that can be
altered through the /C: command-line switch is the specification for which COM
port to use. (The COM port and the baud rate can also be changed through a
debugger command.) Unlike CodeView, WDEB386 runs outside the Windows environment
and does not use WIN.INI or SYSTEM.INI settings to store its configuration.

WDEB386 reprograms the COM port before it sends each character. This feature
prevents other programs or parts of programs that use or abuse the COM port,
such as the MS-DOS MODE command, from influencing the operation of WDEB386. This
prevents misbehaving applications from affecting communication with the
debugger.

WDEB386 is a systems-level debugger for the Windows version 3.0 protected mode
environment (enhanced mode and standard mode). Because it can debug the
initialization portion of device drivers that run under protected mode Windows,
WDEB386 is often used during device driver development. However, for most uses,
CodeView is the preferred protected mode debugger.

In Windows version 3.1, WDEB386 adds the /R: command-line switch to specify the
baud rate.
