Greg,
I am facing some problem in data copying.
I am having a const unsigned char *buf which contains 02 08 00 00 00 00 00 00 f8.
which is copied in port->write_urb->transfer_buffer and sent on ttyUSB0 using
usb_submit_urb(port->write_urb, GFP_ATOMIC).
But I want to send the data bytes is a particular fashion.
1. I want to Add Mark parity.
2. Send the data byte 02 ( Address of a device )
3. Add Space parity .
4. send the data byte 08 00 00 00 00 00 00 f8 ( Null cmd + check sum )
Kindly help me.I am facing the problem in separating the data bytes so that I can send
the data bytes separately using usb_submit_urb.
Thanks,
Raj.
