* This plugin for program plc writes the contents of an SDRAM
* confirmation file to a device using a VS_SET_SDRAM message; the
* CFG file in struct plc must be opened before this function is
* called; the bootloader must be running for this to work;
*
* the VS_SET_SDRAM message is recognized by the INT600 BootLoader
* only; the INT6400 BootLoader recognizes it but does nothing with
* it;
