Hermes or SuperHermes, this is the problem!

Postby Giorgio Garabello » Wed Apr 04, 2018 9:56 am

SMSQ / E with the MACHINE command can detect if Hermes / Superhermes is present. Is there a way to distinguish via software if it is hermes or superhermes in order to automatically load the correct drivers?

Hi Giorgio

Good question. The difference between the sizes of the two extension files is considerable, though nether one is _that_ big (Hermes IPCEXT: 356 bytes, sHermes IPCEXT: 5600 bytes.)

One can leverage the IPCVER$ command which should differentiate between Hermes/sHermes or original 8049, but of course, you need toload one of the two extensions first!

One approach that isn't too waste-full might be:
1. Load the original Hermes IPCEXT
2. Test using IPCVER$
3. IF sHermes detected, then load instead the sHermes IPCEXT equivalent - harmlessly wasting the original 356 bytes.

Not sure how well the two extensions will co-exist, but I suspect the last one loaded will simply take precedence over the first.

Easier still, just load the full sHermes IPCEXT - as per the sHermes manual:

"Other than IPCVER$, the extensions will report “not found” if a non superHermes /Hermes IPC is present or a superHermes-only command is requested on a plain Hermes." - so no harm in loading sHermes IPCEXT on an original Hermes fitted QL.

Good luck!
