The war on RS232

Some more notes about the donated Palm 4 U:

1) Battery life is currently only 2 hours, equivalent to a high end laptop.

2) Accessing the RS232 signals is not trivial. U need to attach a 1% resistor between 2 pins to switch on the serial mode. Complicating the matter, no-one hacks PDA's anymore so all the Google results on doing this are buried

3) PTelnet is the program that converts a Palm into a serial terminal.

4) With the Steve Jobless and Java hype, you'd think a Java ground interface for the donated Palm would be a no brainer. It would take a lot more work and lose a lot of functionality to have a Java ground interface for Palm than a C++ ground interface on a laptop.

Because JVM's are still written in C, operating systems are still written in C, and hardware is still designed for C, C functionality is always going to be several years ahead of Java functionality. In exchange for this, you can migrate a Java program more easily to Windows.
