Hi, After updating to Windows 98 second edition from windows 95, the serial listener I am using (based on the commapi example) can no longer find the serial port. I am getting NoSuchPortException error. I still have the win32com.dll in the jdk1.3 bin directory, javax.com.properties and comm.jar are in jdk1.3 lib. I just can't figure out what went wrong. Can anyone help? thank you in advance. haggai.
