1. ACM function
|
||
|
|
===============
|
||
|
|
|
||
|
|
The function is provided by usb_f_acm.ko module.
|
||
|
|
|
||
|
|
Function-specific configfs interface
|
||
|
|
------------------------------------
|
||
|
|
|
||
|
|
The function name to use when creating the function directory is "acm".
|
||
|
|
The ACM function provides just one attribute in its function directory:
|
||
|
|
|
||
|
|
port_num
|
||
|
|
|
||
|
|
The attribute is read-only.

|
|
||
|
|
There can be at most 4 ACM/generic serial/OBEX ports in the system.
|
||
|
|
|

|
||
|
|
Testing the ACM function
|
||
|
|
------------------------
|
||
|
|
|
||
|
|
On the host: cat > /dev/ttyACM<X>
|
||
|
|
On the device : cat /dev/ttyGS<Y>
|
||
|
|
|
||
|
|
then the other way round
|
||
|
|
|
||
|
|
On the device: cat > /dev/ttyGS<Y>
|
||
|
|
On the host: cat /dev/ttyACM<X>
