Subject: djgpp 1.08 and serial comms under dv/x; demacs To: djgpp AT sun DOT soe DOT clarkson DOT edu (DJ's GPP mailing list) Date: Mon, 21 Sep 92 12:41:24 EDT From: Stephen Turnbull Well, I have joined the group of those who have found GO32 1.08 to be a good way to kill their serial port applications. I was using ProComm Plus, v2.0 to communicate with my mail machine, and trying to run DEmacs v1.2.0 (the Higashida-Hirano port of GNU Emacs to DOS machines) simultaneously under DV/X v1.0 over IBM DOS/V v5.0 (IBM's extended DOS for Japanese; it seems to be fully compatible with MS-DOS 5.0 when in US environment). The machine is AMI 386/33 based with 8 MB RAM. The serial port was able to accept a few characters, after loading DEmacs, before going dead. I have no theories about what is going on, but for those who are working on the problem at present, here is a fairly complete description: 1. start DV/X 2. start ProComm Plus on COM1, connect to host 3. start DEmacs using the following settings in DEMACS.DVP DOS Command: c:\bin\demacs.bat Directory: Memory size: 450 Writes directly to screen: on Displays graphics: off Virtualize text: on Display DOS screen: on Use scaled fonts: on Uses its own colors: off Uses serial port 1: off Uses serial port 2: off Uses math coprocessor: on Allow close window command: moff Close on exit: auto System memory: 0 Maximum program memory size: 768 Maximum expanded memory size: 2048 Text pages: 4 Graphics pages: 0 Protection level: 3 X keyboard behavior: 0 Keyboard conflict: 0 Content of DEMACS.BAT C:\DVX\DVANSI C:\DJGPP\BIN\GO32 C:\BIN\DEMACS ProComm Plus is now in background DEmacs is displaying tutorial screen 4. Click on ProComm Plus, do 'ls' on host, get about 20 characters of response, serial port dies. (Thus, at least a few characters are correctly transmitted, and a few correctly received, by ProComm after starting GO32/DEmacs.) 5. DEmacs tutorial screen disappears in background. (This is why I suspect GO32/DEmacs of grabbing COM1 input. But the tutorial screen may be timed to disappear. Will check later, can't do it now without killing this session.) DEmacs may also have crashed DV/X. However, I have been unable to reproduce that crash. Even if I cannot use DEmacs and communications simultaneously, it is greatly appreciated that I can now run other processes while using DEmacs! -- Stephen Turnbull The Ohio State University, Department of Economics 410 Arps Hall, 1945 N.
