Software flow control is enabled using the IXON, IXOFF , and IXANY constants:
options.c_iflag |= (IXON | IXOFF | IXANY);
To disable software flow control simply mask those bits:
options.c_iflag &= ~(IXON | IXOFF | IXANY);
The XON (start data) and XOFF (stop data) characters are defined in the c_cc array described below.

本文详细介绍了如何使用IXON、IXOFF和IXANY常量在串口通信中启用和禁用软件流控制。通过设置options.c_iflag的位来实现控制,并解释了XON和XOFF字符的作用。
