Why did you disable and enable the 7th bit of T1CON only to set the 7th bit of TMR1H?

I don't understand that.

Doing so will, as per the datasheet, shift the timer clock source to instruction ...

Use this as the interrupt. This uses 3 instructions that do the following.
1) Enable access to the individual bytes of the timer register
2) Add 32768 to timer1 by setting high bit or timer register ...

the ccs c manual does not covers the complete documentation on how to access buffers.

say, i need to enable both receive complete and transmit complete interrupts, and use buffers with conjunction ...

what is the need of logical names?
can't we just use uart1 and uart2?

also, the ccs c manual does not covers the complete documentation on how to access buffers.
