Cyclades 16Ye/PCI, wyse terminal @ 38400 or 19200 bps, xon/xoff handshaking enabled,
regular getty, std.19200 gettytab. very recent current

	

>Description:

The wyse can not re-draw the screen as fast as the host can send the data, so
it sends a stream of xon/xoff chars. this either crashes the port (rendering
it unusable till next re-boot) or the whole machine.

 irq holding problem with an isa wd ethernet card on the same
 machine.
