Int 7A  - Novell Netware - Spx Driver - Get Spx Connection Status          [N]

   BX = 0015h
   DX = connection ID
   ES:SI -> status buffer (see #3499)

Return: AL = return code (00h,EEh) (see also #3496)
       00h connection still valid
       ES:SI -> status buffer filled

Note:  this function is supported by Advanced NetWare 2.1+
