Console redirected to COM1

Tutorials Win: Microsoft Windows Forum

Using wince 6, I added the reg entries to redirect the console to COM1
and to run Subproject1 at boot. Now, Subproject1 will execute CMD

Here is the code!
result = CreateProcess(TEXT("cmd.exe"), NULL, NULL, NULL, 0,
CREATE_NEW_CONSOLE, NULL, NULL, NULL, &new_cmd_exe);


[HKEY_LOCAL_MACHINE\Drivers\Console]
"OutputTo"=dword:1
[HKEY_LOCAL_MACHINE\Drivers\Console]
"COMSpeed"=dword:5c3

[HKEY_LOCAL_MACHINE\init]
"Launch60"="Subproject1.exe"
"Depend60"=hex:14,00, 1e,00

This is what I get on boot on COM1. Note that I am using COM1 for all
boot messages and now want to use it for the shell. You can see below
how I got an invalid handle. Any help is appreciated

You can't share a single serial port for debug printing and
normal serial communications. You will need to disable
debug printing and load the serial driver for it.

This may be not enough. Note that your "Subproject1.exe" may
be executed before the serial driver has been loaded by the
device manager and thus the command shell will simply fail to
open the com handle ...
