Indeed.
Look into the documents and you see:
HSEROUT [Item{,item....}] as HSEROUT [data1] when more HSEROUT [data1, data2, data3]

SERIN Pin,Mode,{Timeout,Label,}{[Qual...],}{Item...}

The Hser... commands are already defined by the statements:
DEFINE HSER_BAUD 9600
DEFINE HSER_RCSTA 90h
DEFINE HSER_TXSTA 24h
DEFINE HSER_SPBRG 129
DEFINE HSER_CLROERR 1

I hope you understand what I meant to say.
In your programm you made a mix of the the both.
