Message-ID: <51370008@hpindda.cup.hp.com> Date: 8 Nov 90 22:06:53 GMT Organization: HP Information Networks, Cupertino, CA Lines: 6 I am trying to install a 3rd serial port to my 386. I can use the 3rd serial port from Dos (as COM3:); however, I can't get to it from Windows 3.0. I get error message saying a DOS application has COM3: locked. Even, I choose to take the device away from the DOS application (from the requester), Windows still come back with a message saying that COM3: is not available. Any idea?
