Red pin numbers are inverted so that bits on set corresponding output pins low and bits off set pins high.

C5 High(bit on) reverse data port for input read only(normally off).

C4 High(bit on) IRQ interrupt off(normally off).

C3 Low(bit on) printer select in.(normally on) OUT32 890, INP32(890) OR 8 turns bit on, pin low.

C2 Low(bit off) pulse Initiate.(normally on) OUT32 890, INP32(890) OR 4 turns bit on, pin high.

C1 Low(bit on) linefeed or auto feed.(normally off) OUT32 890, INP32(890) OR 2 turns bit on, pin low.

C0 Low(bit on) pulse strobe data sent.(normally off) OUT32 890, INP32(890) OR 1 turns bit on, pin low.

WARNING! Software or port hardware controls the port. When C5 is on(32) the Data port is reversed to read data sent from a device. Setting C4(16) can turn off the IRQ interrupt. C4 and C5 have no pins, but can be set internally by a program. Inverted pins are set on when a bit is set low(off). The C0, C1, and C3 pins are inverted while C2 is not. Usually the port sets itself to read 12(C2 and C3 on) after about 30 seconds. Register is used to send messages to a printer or other device that is connected to the port.

S7 High for busy, offline, error.(normally off) INP32(889) AND 128 = 128 when bit is on, pin is pulled lowīit S0 has no pin and can be set at a timeout or reset to 0 by software in EPP mode only.Ĭontrol Register (BaseAddress + 2) Read or Write.

INP32(889) AND 64 = 64 when bit is on, pin is high

INP32(889) AND 32 = 32 when bit is on, pin is high S5 High for out of paper(normally on).INP32(889) AND 16 = 16 when bit is on, pin is high S4 High for printer selected(normally on).INP32(889) AND 8 = 8 when bit is on, pin is high

S3 Low for error, offline or paper end(normally on).

INP32(889) AND 1 = 1 when bit is on (no pin)

S0 Low can be set in EPP mode timeout only(normally off).

Pin voltages can be set to 0 or 5 volts DC by chip devices or grounding switches to turn bits 3 to 6 off or bit 7 on. If the port reads 255 the parallel port is not installed. S0, the timeout bit, can be reset off by software when set by EPP mode.

S7 is inverted so that it adds 128 to the port value when it is grounded. When 5 volts is fed to a pin, bit will stay on. A device can manipulate the read only status port value by grounding certain pins. Pins S3 to S6 are held high by resistors so that it will read 120(or 127) when nothing is connected to the pins. Saddam Khan 20-Sep-11 18:33 20-Sep-11 18:33 Hello Sir, I am really inspired by ur project and i appreciate ur efforts, My Question in Detail: I made two modules in VB regarding Inp and Out done programing, then i send the output to parallel port and i use inp function to get that value from sended port address, it seems my signals are reaching at the port.Status Register (BaseAddress + 1) Read only! Register normally used to monitor the status of a printer or other device that is connected to the parallel port. Object, ByVal e As System.EventArgs) Handles Button1.Click Out(&H378S, &HFFS) ' Print '1' to D7-D0 or 255 in Decimal Dim Value1 As String ' String named Value1 Value1 = Inp(&H378S) ' Now Value1 has the values in 'data port' MessageBox.Show(Value1) ' A popup will indicate the current value written End Sub Thanx.

Ok, this is for the Status Port, But my problem is with the Data Port again with the code, the following code I'm using for the data port, the results should be 255 but I got 120. Some of the pins must be connected to GND to change, some need to be connected to +Ub.

Be sure to use the electrical side correctly.
