Do yourself a favor and search the Texas Instruments, Maxim and Linear
Technology web sites for their applications notes on Li-Ion battery
charging. They will tell you all you need to know about the subject. 

For debugging applications using RS232 you may be thinking of Bray++
Terminal or RealTerm. Google for either -- they are both great tools
for RS232 development work.
