You must use .BAT for Windows XP. For Windows Vista and Windows 7 you can use either .BAT or .CMD files.

Install ProBoard using the install.exe. Go to your ProBoard root directory.
Most common root directory for ProBoard is: C:\PB
In a DOS Prompt Window (Not DOSBox Window) type edit runpb.bat or edit runpb.cmd.
Your RUNPB.BAT or RUNPB.CMD should look like this.

@echo off
set proboard=c:\pb
SET INOTE=C:\PB\DOORS\INOTE
cd\pb\node%1
\pb\proboard.exe -B115200 -N%1
erase socket.txt

Unzip the NetFOSS ZIP file into C:\netfoss to install NetFOSS. Right click your
NET2BBS.INI file in Windows Explorer and click edit. Make sure where it is says,
"Edit only lines after the [Settings] line below," that your NET2BBS.INI file looks
like the the sample below.

Your NF.BAT or NF.CMD should look like this.

@echo off
c:\netfoss\netfoss.com %1
echo %2>socket.txt <----- This line is optional and only needed for DOOR32.PEX
rem ** If running a non-door32.sys system, add a " %1" to end of above line **
if errorlevel 1 goto end
c:\netfoss\netcom.exe %1 %2 %3 %4 %5 %6 %7 %8 %9
c:\netfoss\netfoss.com /u
:end
