Updated jm_fullduplexserial.spin2 For PNut v37, FlexProp, Propeller Tool
The latest version of PNut, v37, has a new keyword that collides with a symbol inside jm_fulldupexserial.spin2 (yes, we've been down this road before). I believe that Eric has already made FlexProp compatible with v37, so it may raise its head there, too.
The attached version of jm_fullduplexserial.spin2 changes the conflicting symbol name.
I tested in PNut (v37) and FlexProp (5.9.20). Propeller Tool hasn't folded in the new compiler yet, but you should update your library with this version.
