Hi all,
I need to implement a kernel space module that acts like a serial port "proxy". The idea is to access this "proxy" module from user space and then retransmit some modified content to the ttyS device. This module will also take care of additional (hardware specific) fuctionality required by the modem (an EHS modem).
The problem is that I can't comunicate with the tty driver trough its device file because of the sys_call_table race conditions.
Is there a way to do that in a separate module (a proxy module) and not modify the serial driver (it's tty_io)?
Thanks in advance.
Best Regards,
