But how do you use setting baud rate and parity, etc ... on a bluetooth
dongle?
Baud rate, parity and stop bits off course makes no sense. What you can
do is sending control signals (BRAKE, DTR, CTS) that's what we need.
You add a quirk which causes the probe() method to use another function here:
acm->urb_task.func = acm_rx_tasklet;
and
tty_register_device(acm_tty_driver, minor, &control_interface->dev);
interesting.
In static int __init acm_init(void) you define a second driver with an altered
set of tty_operations that defines a different acm_tty_write()
Can you post "lsusb -v" for your device?
sure:
