I am using i.MX28 AUART1 for communication with XBEE module, in which i need hardware flow control.
When i open minicom with H/W flow control enabled. RTS line of Processor never goes low. because of which
there is no communication happening at all. But when i Connect RTS of Processor to CTS of XBEE and then
CTS of Processor to RTS of XBEE (Note that i do it in sequence that is manually with wires with some delay) It starts working.
if any one have any Idea why is it behaving like this, Please help.
