There's a ton of stuff on the MicroChip website - did you even bother to look?  Or even Google?

If you insist on being spoonfed, these will get you started:

Hello,

there is a nice Project for expecially dsPICs. It is possible to generate up to 8 UARTs using DMA technique with general IO pins. Since it is not a software UART, there are less latencies compared to softUart.

Here is a link to a post, you also find the code there:
