这边有个问题请教各位大侠 :

LPC2468 uart interface :uart0,uart2 and uart3 without RTS and CTS,can we configure GPIOs to equal these two pins (RTS and CTS ) function?

thanks

LPC2468 has four Uarts and only one uart1 with modem interface , but I want two Uarts for using !
because the RTS and CTS are both control signals ,so I want to think wheter we only configure I/O to implement this control function .not adding external materials?
也许我的问题有点白痴 ,见笑!

如果要模拟肯定可以的.这些信号和RX TX没有必然的联系.修改驱动部份的程序应该就可以了
