No time to check it now but there's either a win98 or win32 flag to laddie command line that made it work on win98. You need to install the .net framework 2.0 and use the flag. The purpose of the flag is that it makes it use the win32 serial API directly. The 2.0 framework didn't support serial port so that was a workaround.
It might fail to run for some other reason but it's supposed to work on 98. -- John .
