This template is used to populate the Device Infobox with information about a simple IO controller card. See AB-862G Super I∕O Card for example use. As this template sits inside an infobox, it can be combined with other templates in the case of multi-function devices.

Valid parameters and examples specific to this infobox are:

Parameter Meaning
Serial ports = Value Number of RS232 ports the device supports, including internal connectors.
  • 0 if none
  • 1 if only one port
  • 2 for two ports, and so on.
UART = Value Only shown if Serial ports is greater than zero.
Text value for the RS232 interface chip. One of:
  • 8250 - original, 1-byte buffer, one interrupt per byte received
  • 16450 - 16550 but with no FIFO buffer
  • 16550 - early 16550 with broken FIFO buffer, effectively a 16450
  • 16550A - fixed 16550 with working FIFO buffer
  • 16650 - early 16650 with broken FIFO buffer
  • 16650V2 - fixed 16650 with working FIFO buffer

Add others to this list as needed - try to be as generic as possible, avoiding part names and using interface names instead.

COM1 = Value Only shown if Serial ports is greater than zero.
Boolean value. Can one of the serial ports on this card be set to COM1? Y if yes, N if not.
COM2 = Value Only shown if Serial ports is greater than zero.
Boolean value. Can one of the serial ports on this card be set to COM2? Y if yes, N if not.
COM3 = Value Only shown if Serial ports is greater than zero.
Boolean value. Can one of the serial ports on this card be set to COM3? Y if yes, N if not.
COM4 = Value Only shown if Serial ports is greater than zero.
Boolean value. Can one of the serial ports on this card be set to COM4? Y if yes, N if not.
Parallel ports = Value Number of IEEE1284 (incl. pre-IEEE1284/Centronics) ports the device supports, including internal connectors.
  • 0 if none
  • 1 if only one port
  • 2 for two ports, and so on.
Bi-dir = Value Only shown if Parallel ports is greater than zero.
Boolean value indicating whether the LPT interface can operate in bi-directional mode, perhaps set via a jumper.

If Y, the port can send and receive whole bytes in one go over the same eight data lines. If N, the port can only receive bytes in two halves, by re-purposing the four printer status lines.

ECP = Value Only shown if Parallel ports is greater than zero.
Boolean value indicating whether the LPT interface can operate in ECP mode, perhaps set via a jumper.

If Y, the port can send and receive whole bytes in one go over the same eight data lines, using the ECP interface. If N, the port may still be able to do this, but not via the ECP method.

EPP = Value Only shown if Parallel ports is greater than zero.
Boolean value indicating whether the LPT interface can operate in EPP mode, perhaps set via a jumper.

If Y, the port can send and receive whole bytes in one go over the same eight data lines, while using ISA DMA to minimise CPU usage. If N, the port may still be able to transfer whole bytes at the same time, but it cannot make use of DMA to reduce CPU utilisation.

LPT1 = Value Only shown if Parallel ports is greater than zero.
Boolean value. Can one of the parallel ports on this card be set to LPT1? Y if yes, N if not.
LPT2 = Value Only shown if Parallel ports is greater than zero.
Boolean value. Can one of the parallel ports on this card be set to LPT2? Y if yes, N if not.
LPT3 = Value Only shown if Parallel ports is greater than zero.
Boolean value. Can one of the parallel ports on this card be set to LPT3? Y if yes, N if not.
LPT4 = Value Only shown if Parallel ports is greater than zero.
Boolean value. Can one of the parallel ports on this card be set to LPT4? Y if yes, N if not.
Game ports = Value Number of game ports (PC-style joystick ports) the device supports, including internal connectors.
  • 0 if none
  • 1 if only one port
  • 2 for two ports, and so on.
