>Doesn't MFNet use TCP/IP? Yes, that is the media to communicate with the PC if you do not like to use special HW for FICON, ESCON.
>Software that emulates a device like MFNet could be done with a supported means/interface NO. MFNetDisk uses code to catch all the IO. MFNetDisk uses sometime STARTIO when it required to do so. STARTIO uses the lowest level of MVS for IO. That is the important issue. Better not to use the start IO for doing IO. To do IO, better use READ,WRITE this will lower your possibilities to make bugs. StartIO is almost like adding your driver (in PC) to your program to issue IO.
