well, my version of SMP.INF here (from 1997) doesn't mention
DosCallPSD; the same with OS2?86?.LIB, and in the symbol files of
OS2KRNL whis call is missing, too. DosTestPSD is implemented and made
public, the question remains what about DosCallPSD?

At least this is what SMP.INF tells about PSD_APP_COMM in the
documentation of the PSD entry points.
