I became using 29 Palisade driver which I rejected at first and found
special mode for my GPS Receiver Trimble Thunderbolt (mode 2).
But for correct work I had to put little changes to code - file termios.c :
function int ioctl_tiocmset()
I put "!" before each call to EscapeCommFunction()
Now it is work.
