A question concerning 3270 bisynch.  Does anyone know if an
RVI followed by status sense response of "DEVICE BUSY" is 
a legal response to a host device selection?  The 3274 
Control Unit description manual indicates that it is,
but it is not clear.

If a device is busy when a host tries to select it, should
a WACK be used to respond or can the above mentioned 
status sense message of "DEVICE BUSY" be used?

Any help or comments would be appreciated.


Thanks in advance,

Mario Arias
