Message-ID: <944@gumby.WISC.EDU> Date: Mon, 13-Jul-87 10:18:57 EDT Article-I.D.: gumby.944 Posted: Mon Jul 13 10:18:57 1987 Date-Received: Tue, 14-Jul-87 03:10:51 EDT Organization: U of Wisconsin CS Dept Lines: 17 Keywords: amiga serial resources parallel After reading the posting of Philip Lindsay (thanks) on how to access the paralle port, I was able to convert it to gain access the serial port resource. However, there seems to be one problem: After some program finishes using the serial device(like the aux: handler), the MR_SERIALPORT is not automatically freed, resulting in a failure when my program tries to gain access. My goal is to have multiple programs co-exist under the multi-tasking enviornment, each gaining the access to the serial port only when necessary. So here is my question: Is there any way to force the serial device to release the access on MR_SERIALPORT when it is not serving anybody?
