Sorry to post to the entire list, but all attempts to reply to Pawel directly have bounced
============================================================
Are you using a local serial port or a network/serial adapter?  On what operating system platform?
We didn't provide access to all termios settings in the set of asyn get/set options.   

ixon/ixoff is a rather non-robust flow control mechanism since if any XON is lost or mangled for some reason the port locks up forever.  Is there no way that you can use hardware (CTS/RTS) flow control?

If your IOC is running on linux/darwin/solaris you could try running a
system("stty ixon </dev/xxxxx")
command from the st.cmd script after opening the serial line.  To enable the system command you will need to add 'system.dbd' to your application's list of dbd files.

We tried to activate the "ixon" option in the serial port configuration but it in not recognized. Can you give us a hint what else could we do ? The control characters spoil the pattern recognition by the streamDevice driver unfortunately...
