When I use ZiLOG Standard Libraries in my application and build from
the command line, why do I see unresolved errors? . . . . . . . . . . . . . . . . . . . . . . . . 314
I do not use the standard boot-up module, but I have manually included
ZiLOG Standard Libraries. When I link my code with the library, why
do I get an unresolved symbols error? . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 314

I need to change the ZSL source code. How can I generate a new library
with these changes included? . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 314
How can I use standard I/O calls like printf() and getch()? . . . . . . . . . . . . . . . . . . . . . 315

How can I change the default UART settings for my application? . . . . . . . . . . . . . . . . 315
I am using the UART in the interrupt mode. Why do I seem to lose some
of the data when I try to print or try to receive a large amount of data? . . . . . . . . . 316
When I call open_UARTx() function by configuring it in INTERRUPT mode,
the control never comes back to my program and my program behaves
indifferently. Why is this? . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 316
