Hi all,
I'm trying to manipulate the DTR signal of the serial port.
As an example I used this code snippet: http://lists.exploits.org/upsdev/Feb2004/00013.html.
I can open the com1, I can send and receive data but the ioctl I use
to read the status of the signals returns -1:
int status;
ioctl(upsfd, TIOCMGET, &status);Anybody can help me? I have no idea about what's wrong with this code.
Thanks a lot in advance,
llandre
