Almost all of InRoads exporting is done with reports. The source for the reports is almost exclusively XML.
Reports in turn, export ASCII, HTML or XML. Reports can do this from various points within the product. InRoads Survey Codes are store in the XIN file - which is XML and certain report style sheets can convert them to ASCII, HTML or XML.
Unless the TPS or some software it uses supports importing codes in ASCII, HTML or XML, I suspect you are out of luck. You probably need to contact Leica to see what they recommend.

There is an Export Leica DBX 1200 tool in the Tools->Application Add-ins for InRoads. I'm not sure if this is the same as the total stations but it may be worth giving it a try.
