-> I have been using OS/2 to run my BBS since feb. 1996 and have yet to   
   -> find a DOS program that doesn't work under OS/2+DOS.   
      
   Borland C++ 3.1 fails.   
      
   -> The BBS is running under Warp 4 FP12.   
      
   FP12 seems good here too. But I had to use IBM1S506.ADD from MCP2 to get   
   my SIS IDE controller using UDMA.  And the IBM com.sys driver from MCP2   
   works with my PCI serial card.   
      
   Running a stress test with SIO (1.60d) shows that it uses 100% of the   
   CPU on an inbound transfer at 115200. The IBM com.sys only uses 3% on   
   the same test. SIO gives the app many small packets, hammering the CPU.
