Changes the port associated with the given DMA channel to be used in the programmed I/O mode. This service is for use only on PS/2 computers. The Windows 95 I/O subsystem uses this service to determine if the port associated with a DMA channel is in its default location. In most cases, there should be no need for any other VxD to use this service.

• No return value.

Channel_Number

Number of the channel.

Port_Number
