hpe5250a_dcl
This function sends a device clear (DCL) to the instrument.
A device clear will abort the present operation and enable the instrument to accept a
new command or query.
This is particularly useful in situations where it is not possible to determine the
instrument state. In this case, it is customary to send a device clear before issuing a
new instrument driver functi on. The device clear ensures that the instrument will be
able to begin processing the new commands.

Parameters vi Instrument handle returned from hpe5250a_init( ).
