// 
// There are five control input pins. 
// Make one of them in the below list uncommented:

// Pin 10 of the status port has a pull up resistor in the PC.
// In case you use one of the other pins, connect it in parallel
// with pin 10 to make use of the pull up resistor (or add an external
// resistor to +5V)

// *******************************************
// 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
// These are the control port output pins:
//   1  =  bit0 = Strobe (output)
//  14  =  bit1 = Auto Feed (output)
//  16  =  bit2 = Initialize Paper (output)
//  17  =  bit3 = -Select Input (output)

// These are the status port input pins:
//  10  =  bit7 = Acknowledge (input)
//  11  =  bit6 = Busy (input)
//  12  =  bit5 = P.End (input)
//  13  =  bit4 = IRQ (input)
//  15  =  bit3 = Error (input)

// Two output pins of the control port are used to clock serial 
// data into the selected unit and one output pin is used for
// the transmit/receive switching.
// "Strobe" = pin 1 is clock.
// "Select input" = pin 17 is the serial data.
// "Auto Feed" = pin 14 is the transmit/receive control pin.
