Does BSP Serial Port Driver support DSR, CTS and RING signal?

When I use serial port for modem connection I see in debug:

142423 PID:400002 TID:3900012 Warning!!! : WaitCommEvents EV_RING not suppported!!!
142423 PID:400002 TID:3900012 Warning!!! : WaitCommEvents EV_DSR not suppported!!!
142424 PID:400002 TID:3900012 Warning!!! : WaitCommEvents EV_CTS not suppported!!!

and connection doesn`t establishing. In RAS window I see "Authenticating User"

Hello,

The modem fonctionnalities aren't supported by the UART driver. The processor AT91SAM9263 doesn't have any DTR, DSR, DCD and RI signals either.

So if you want to use the modem mode on the uart you'll have to emulate those signals by software.

Kind Regards,

Do I need write new serial driver, or I can do this with existing driver?
