Message-ID: <CpJyHw.D2E@du.edu> Sender: news@du.edu (USENET News System) Organization: University of Denver Date: Mon, 9 May 1994 20:34:44 GMT Lines: 19 I'm trying to get the 6 port Boca card working on 1.1-RELEASE. I've built a kernel with COM_MULTIPORT, and can talk to the ports (set up as sio2-7 above 2 standard ports) but I seem to get delayed output (apparently always one operation behind). This is for output only, no getty running and BI_DIRECTIONAL disabled. My guess is the problem relates to the lack of a "master port" interrupt, and possibly the interrupt register address. The system does see all the ports when it boots and reports no problems at that time. I've been through all the docs I can find, and looked at sio.c in current, which makes references to some of these issues (master port) in ways that are different from the RELEASE sio.c, but I'm not sure I can use the code in current alongside the RELEASE kernel. The ports work fine if I set them up for unshared interrupts as standard COM1 and COM2. -- Thorn Roby troby@diana.cair.du.edu CARL Systems, Inc. troby@carl.org 3801 E.
