5-29. Programming the STB and SRE
By resetting (to 0) the bits in the SRE, you can mask (disable) associated bits in the serial
poll status byte. Bits set to 1 enable the associated bit in the serial poll status byte. The
following sample program enables the Error Available (EAV) bit.

INPUT @6, A%
50
PRINT "SRE = ";A%

RETURN
! LOAD THE REGISTER
! ASK FOR THE SRE CONTENTS
! RETRIEVE THE REGISTER CONTENTS
The following program generates an error and checks the Serial Poll StatusByte. Enable
the EAV bit with the examples above.

A% = SPL(6)
! DO A SERIAL POLL
