Ho there,
This is the next step in my quest for video-interaction.
In order to experiment with the setup, I have a Philips
VP 410 Laservision Disc Drive connected to my PC (386SX)
over the RS232. I found a very neat Pascal communication program
in wuarchive.wustl.edu, that makes it possible to send
ASCII commands over the Com1 (RS232) to the video-player.
And it works fine. (The program is called Comm-TP4 and is
written by Kevin R. Bulgrien.)
Alas, the program is much too big, since I have to call it
from within an other (presentation) program that already
swallows most of my PC's memory.
The question : where do I find a program that does the same
thing and is much (!) smaller. This means : it doesn't have to
have any user-interaction facilities, it just must be able
to send the ascii commands to the laser disc drive over Com1.
Commands like : ,1 (stand by)
F00001N (goto picture number 1 and start playing)
,0 (stop).
I did find a few hints in the Pascal manual, but it refers
to the IBM technical manual, and from there on it gets much to
complicated for me, a Pascal- and PC-beginner.
Any help would very much appreciated.
Peter.

[...deleted...] Perhaps I'm suggesting an overly simple approach, but have you tried initializing the com port (via a DOS MODE command (from a batch file or an EXEC call) or by using the appropriate BIOS call or some other means), then merely using WriteLn(Com1,',1'), etc.? +--------------------------------------------------------------------+ | Karl Brendel Centers for Disease Control | | Internet: CDCKAB@EMUVM1.BITNET Epidemiology Program Office | | Bitnet: CDCKAB@EMUVM1 Atlanta, GA, USA | | Home of Epi Info 5.0 | +--------------------------------------------------------------------+
