Cyclades 16/Ye/PCI. -current kernel a few days old + patch for the
cy cuac* DCD transition bug.

Wyse terminal at 19,200 bps with XON/XOFF handshaking, vt100 mode
attached to ttyc0e. standard getty, std.19200 gettytab

speed 19200 baud; 0 rows; 0 columns;
lflags: -icanon isig iexten -echo echoe -echok echoke -echonl echoctl
        -echoprt -altwerase -noflsh -tostop -flusho -pendin -nokerninfo
        -extproc

cflags: cread cs8 -parenb -parodd hupcl -clocal -cstopb crtscts -dsrflow
        -dtrflow -mdmbuf
cchars: discard = ^O; dsusp = <undef>; eof = ^D; eol = <undef>;
        eol2 = <undef>; erase = ^?; intr = ^C; kill = ^U;
        lnext = <undef>; min = 1; quit = ^\; reprint = ^R; start = ^Q;
        status = <undef>; stop = ^S; susp = ^Z; time = 0; werase = ^W;

(same prob with -crtscts too)

	

>Description:

The wyse terminal can not keep up at 19200 and so sends XON characters as
flow control.

As a result system reboots/panics (not sure which, no console).
