Int 2F Fn 111C  CU - Network Redirector - Findnext                         [N]

   AX = 111Ch
   SS = DS = DOS DS
   ES:DI -> CDS
   ES:DI -> DTA (MSDOS v5.0)
   [DTA] = 21-byte findfirst search data
         (see #1312 at INT 21/AH=4Eh)

Return: CF set on error
       AX = DOS error code (see #1366 at INT 21/AH=59h/BX=0000h)
   CF clear if successful
       [DTA] = updated findfirst search data
           (bit 7 of first byte must be set)
       [DTA+15h] = standard directory entry for file (see #1041)

Note:  this function is called by the DOS 3.1+ kernel
