How can I use the BusTools/1553 API to wrap data between two RT SA combinations?

The following example shows you how to receive a command sent to RT 5, SA 3 and wrap it to RT 5 SA 12. This is done by using the default buffers. These are selected by programming BusTools_RT_CbufWrite with a buffer count of 0. This wraps the data into the transmit buffer. You can use this method for all RT and subaddress combinations. See the following example:

*  Output RT control buffers
*   Enable or disable all word counts and mode codes as specified by
*    the caller's arguments.

#define RT_ADDR 5   

cbuf.legal_wordcount = 0xffffffff;  // legalize all word counts
for ( tr = 0; tr
