MacDFT, PF10 Function, and 32798 Error



I am running MacDFT on my Macintosh IIcx, with System 6.0.5. I am accessing
PROFS from our mainframe. When I ran version 1.0 of MacDFT I was okay, but
as soon as I upgraded to version 1.1, I began experiencing problems when I
used the PF10 function. The system hangs and reports a 32798 error and that
communication with the host has been lost. I did try switching settings
within the program, but to no avail. We are using a coax connection.

A 32798 error is a TIMEOUT_ERR, or "request timed out" and suggests a
problem between the terminal and controller. We have seen similar problems
when a non-IBM controller is used (Apple only supports IBM 3x74
controllers). And this type of error is much more prevalent when one is
using DFT mode as compared to CUT.

MacDFT 1.0 only supported CUT mode, and MacDFT 1.1 supports either. You
may be able to use MacDFT 1.1 in CUT mode to work around this problem.
However, you may encounter other incompatibilities if you are not using IBM
controllers.

A PF10 from the PROFs main menu is an add-on automatic reminder. This
worked flawlessly for us during our testing with MacDFT 1.1.

Another possible problem area is the type of cable used. When coaxial
devices are designed, we usually assume RG62/AU, but often unshielded and
less-expensive cable is substituted, like RG59 or RG58. Either of these
latter two cable types could cause problems.
