[net.micro.pc] Bug in Quadboard parallel port

peterr@utcsrgv.UUCP (Peter Rowley) (10/11/83)

I've recently switched from a first-generation IBM parallel adapter card
to a Quadboard.  It works fine, except for one apparent bug:  if the
printer (an Epson MX-80) is off, the Quadboard seems to indicate to
BASIC that it is both on and selected.  If the printer is on, the select
status is correctly reported to BASIC.  I believe the IBM card properly
reports the printer as off when it is.  Have other people had this
problem?  Is there any sure fire method a program can use to determine
whether or not the printer is on when using a Quadboard?  A mistakenly-off
printer has caused me to lose some output to the bit-bucket.
