Send Device Clear; Send Remote Enable
Send 10740A Backplane Reset, preset x-axis counter and
select normal resolution
Transfer x-axis counter (10760A) contents, including error
bits to 10745A.
If SRQ false; reference error bit must be false; laser ready
Read 10745A STATUS BYTE to verify that it is
asserting SRQ.

Otherwise, use subroutine "check" to identify remaining error
Return to step one if only ovf error true
