SL6087-UART1 handshake signals

Will SL6087 and/or OpenAT 7.43 allow DSR1,DTR1,CD1,RI1 to be subscribed to as GPIO
when UART1 is active?WMP100 and/or OpenAT 7.3A would not allow this.Due to the small number
of GPIO signals available on SL6087,this would be very helpful.

Hi
Have you checked the Product Technical specification(i.e. PTS) for SL6087 for this info???
