How can I read/write to the parallel or serial ports in XB?
There is not currently a built-in x-platform library for port communications. There are direct APIs that can be called from Win9x API functions. The following are the Win9x API functions used with communications resource (kernel32.dll). A communications resource is a physical or logical device that provides a single bidirectional, asynchronous data stream. Serial ports, parallel ports, fax machines, and modems are examples of communications resources. See kernel32.dec.
