PIC to PIC Serial Communications?

[J. Mark Wolf]

I am working on a joint project with another programmer in another area to communicate some data between our PIC processors.

We have chosen serial comm to do this. Can we simply connect the TTL levels together between PICs or must I use level converting chips?

He is writing to hardware with C code I believe and I am using PICBASIC PRO Serout/SerIn. Does any of this have any bearing as far as inverted signals etc. are concerned?

Yes, this is commonly called SCI, and I've been doing it for years, on 15foot long cables through automotive environments.
