Nope, it must be:

DECLARE LONG SisPublicReadCard IN SisPublic.dll STRING @
STORE REPLICATE(CHR(0),404) TO cTest
? SisPublicReadCard(@cTest)
? cTest

and the function returns
PC/SC error code
SCARD_S_SUCCESS if ok
SCARD_E_INSUFFICIENT_BUFFER if pucBuffer is NULL
You must know values for these predifined constants (they must be defined in some of header files that comes with that dll).
