I hadn't heard the bit about mapping serial operations to the springboard.
However, there was one change I had to make to the Palm OS Emulator's ROM
Transfer tool (actually, Handspring made this change, not me):
On Visor Standard and Deluxe, there is a thread looking for a keyboard attached
to the serial port. If you want to use the serial port, you have to disable
this thread first.
// <chg 02-01-2000 BP> If on Handspring device, disable the keyboard
// thread before opening the serial library.
if (!FtrGet ('hsEx', 0, &ftrValue))
HsExtKeyboardEnable (false);
On Platinum, there's something else going on. When I call SrmOpen, I get error
0x2000. I can't find this documented anywhere (the Palm headers show 0x2000 to
be an Activation application error code), and haven't had a chance to talk with
Handspring about this yet.
I haven't tried Prism, yet.

I read somewhere that the serial port gets mapped automatically on the
springboard slot (for modem springboards, I gather). This was true for the
Visor / Visor deluxe, and may have changed on the newer models. I can't
remember where I read this, nor can I remember if there was a way to work
around this problem (i.e. opening a serial port on the cradle interface).
I realize that this information isn't very useful. Maybe someone else can
fill in the details?
John.
