2020i Serial port
I am developping a program that use serial port to connect a device.
That device use 2 wire communication (only RX and TX) so i set
2020i Serial in order to disable hardware handshake and modem
controls (CTS, RTS, DTR and DSR). But it doesn't works!!!
I investigated and i found that 2020i uses Standard UART port
(Address 0x4070000). Datasheet of pxa270 says that Standard UART
doesn't manage modem control, so why my 2020i needs it? Is there
some other hardware that controls serial port inside? How could i
disable hardware handshake?
And last, had someone connected a GPS receiver using serial port of
I know that perhaps it is a too tech topics, but if someone can help me...
