UART Flow control

Other Parts Discussed in Thread: TM4C129XNCZAD

Hello,

(TM4C129XNCZAD  based custom board  talking to a TM4C129NCPDT over UART. TI-RTOS  2.14, CCS 6,1, TI-ARM compiler 5.25)

We want to implement flow control for the UART communication between 2 boards.  I have looked into the TI-RTOS UART driver and it supports only hardware flow control.  We are short of I/O pins to make use of hardware flow control.  Is there anyway we can have software flow control in TI-RTOS UART driver

Thanks
