I am working on a project using SunOS 4.1.3 iand the ttya and ttyb
serial ports and ioctl's defined in termios.h. I have programmed the
serial I/O channels to employ XON/XOFF handshaking. My question is:
what code will find out the last flow control character received by the
Sun serial driver, i.e. did it receive an XOFF and is currently
paused? or did it get an XON and is/can send out characters.
Thanks for any tips. Please respond directly to:
