Serial Ports and RR

[David Vaughan]

Gene

Thanks for that. So far I have failed to get the Script Editor to 
compile and use even the sample scripts provided with the Serac 
additions but then I am not an Applescript user anyway. I was sold a 
Taiwanese thingy as a functional equivalent of the Keyspan. It  is 
recognised by the system profiler and I should find out today if it 
works under OS X. If I can capture data, as I hope, using ZTerm then  I 
will try using Rev accessing a "modem" port.

In case of idle interest, my application is logging charge/discharge 
data from Schulze and Orbit NiCd/NiMH/LiIon fast chargers as used for 
electric flight and 1/10th model car racing. Their data ports use only 
TxD, RxD and Gnd at 9600b/s so the interface is uncomplicated once I get 
the drivers right. The factory-supplied apps are fairly basic and run 
only under Windows, whereas I want to examine multiple data sets in Data 
Desk, to compare charging rates and methods as well as the batteries 
themselves.

regards
David
