Re: Super Serial Support in Emulator (How to use it???)

[rdoerr@bizserve.com (Robert L. Doerr)]

Hello Oliver,

Thanks for the post.  Do you know if it is possible to add the image of
the other ROM to make it more compatible with the SuperSerial card?

I have this one application that I have to have an Apple IIe to run.  It
would be fantastic if I could get it to work within the emulator and talk
to its communicator via the serial port.  I will always keep a real Apple
around but it would enable the software to run on a modern laptop which is
much easier to carry around than an entire IIe system.

The emulator from Apple Oasis seems to support the SuperSerial card and
my program recognizes it.  Someone suggested that it may not implement all
the hardware emulation of the serial chip though.  I still need to confirm
the differences in the 25pin serial port on the Apple and a 9pin serial
port for a PC so I can make sure my cable is correct.  If I have it wired wrong
then that could be the problem and the emulator from Apple Oasis may work.

If it ends up that the issue is that the emulators all offer partial support
(in different ways) I am still stuck.  I can only hope that it will be added
in the future.  I don't have the resources to attempt that myself but could
work with the authors of the emulators to test any new variation that would
include full Super Serial card support to see if they work with my application.

Thanks,

Robert
