Summary:

The CodeView sequential mode (/T option) is no longer supported

beginning with CodeView version 3.0.

More Information:

In CodeView versions 2.35 and earlier, the /T option caused the

debugger to operate in "sequential mode," which means that only a

command-line interface was available. You could then type the command

"=COM1" to redirect the input and output to the COM port, which

allowed debugging via a remote terminal.

The /T option and the "=COM1" command are not available beginning with

CodeView 3.0 because of the new windowing environment used in these

versions.

However, you can still redirect CodeView output to COM1 using the

Redirected Output command.

The Redirected Output command causes the CodeView debugger to write

all subsequent command output to a device, such as another terminal, a

printer, or a file. The term "output" includes not only the output

from commands but also the command characters that are echoed as you

type them.

The second greater-than symbol (optional) appends the output to an

existing file. If you redirect output to an existing file without this

symbol, the existing file will be replaced. For example:

>>COM1

In the example above, output is redirected to the device designated as

COM1 (probably a remote terminal). You might want to enter this

command, for example, when you are debugging a graphics program and

want CodeView commands to be displayed on a remote terminal while the

program display appears on the originating terminal.

>>OUTFILE.TXT

In the example above, output is redirected to the file OUTFILE.TXT.

This command is helpful in keeping a permanent record of a CodeView

session.
