You're in for a tough time of it using IND$FILE.  When you have the McData
controller switched to the ASCII host, the controller does the conversion
of the 3270 blocks to/from ASCII.  This means that when you try to run
IND$FILE, the controller will convert the IND$FILE blocks into ASCII,
rendering them garbage.

If you are tring to transfer ASCII data only, you might have better luck
writing PC programs that talk to the IRMA card and have the data transfered
via screen buffers.

We (Motorola) did a project several years back whereby we connected a
McData controller to our Unix box via a Multi-bus to VMEbus connection
of our own design.  This allowed COAX terminals and PC's access to Unix
as well as Unix ASCII terminal access to the host.  The only way we could
transfer files between the PC and Unix was to first transfer the file
from the PC to the IBM host, then, from Unix, transfer the file from
the IBM host to the Unix system using an IND$FILE transfer that runs
under Unix.  (No, I can't give you any source for this. sorry).

Good Luck.
