' This program shows the status of jumper 1 on the lines of port A.
' To address correctly the ETI 324 board on ABACO(r) I/O Bus, you should
' configure the board to match the hex 80 address, to do this switch to OFF
' the switches from 1 to 4, switch to ON switch 5.
' To achieve the visualization of the lines, you should connect the CN3
' connector of GPC(r) 324 board to the CN15 connector of DEB(r) 01 board by
' a 20-pin flat cable.
