You might check with a TDSDUMP log that the parameter is being returned. 
Example from src/odbc/unittests/const_param.c:

0010 04 b1 cb 74 00 fe 00 00-e0 00 01 00 00 00       |...t.... ......|

Memo to file: it would be nice if the output parameter values (and return
status) appeared in the log, so we'd know what the user could expect to
see.  

HTH.
