Origin Version (Select Help-->About Origin): 7.0
Operating System: Windows 2000
Hi,
I am trying to transmit data to an external device, connected to the computer via the RS-232 port (in my case: COM 1)
What I eventually want to do is clicking into a .bmp image, imported into Origin and having Origin send the coordinates to an external device, which moves to this position.
Anyway, my problems start much earlier:
I tried to communicate with a simple RS-232 device, tried the file RS232commands.c from the data exchange site and the RS232.c file shipped with Origin itself.Neither worked. Communication with Microsoft "Hyperterminal" works, though.
Required RS-232 Settings are
Baud Rate: 9600
Parity: none
Data bits: 8
stop bits: 1
I tried commands like (RS232commands.c):
rs_open(1);
rs_write("*rst\n");
result:
COM1 was opened successfully. (nothing else)
or with RS232.c:
rso 1;
rsw "*rst\n";
result:
COM1 was openned successfully.
6 bytes chars have been sent COM.
The command for the device is *rst and \n is the message terminator. Is the message terminator maybe the problem ? I tried it with and without.
In order to get to the final goal (clicking and transmitting via RS232, is Winedge maybe the better choice for that task ?
Sincerely
Oliver Kiowski

Hallo Oliver,
I just stumbled into a similar problem with Origin7.0 (and I realy do not whant to upgrade)...
Maybe it is causing your problem too:
There is a BUG inside the definitions in mscomm.h
if I write:
if ( !SetDCB( hCom, 19200, 8, 0, 1 ) )
it is working -
instead of:
//if ( !SetDCB( hCom, BAUD_19200, 8, NOPARITY, ONESTOPBIT ) )
which is not working...
best regards
