// Radio hardware control is through the parallel port.
// Each hardware unit is controlled by serial data that is clocked
// into a shift register.
// The data in the shift register is transferred to a latch after
// the complete word has been transferred.
// The 8 bits of the output (data) port are used to select
// a hardware unit.
// If all 8 bits are zero, no unit is selected.
// In a small system with maximum 8 units, the 8 data
// pins can be used directly to select one unit each.
// By decoding the 8 bits one can select up to 255 units.
// The number of wires would become impractical and some
// other communication is recommended.
// These are the data pins on the 25 pin d-sub:
//   2  =  bit0
//   3  =  bit1
//   4  =  bit2
//   5  =  bit3
//   6  =  bit4
//   7  =  bit5
//   8  =  bit6
//   9  =  bit7
//
// The control port is used to clock serial data into the
// selected unit. 
// "Strobe" = pin 1 is clock.
// "Select input" = pin 17 is the serial data.
