It seems that Hserin cannot accept a word array in this expression:

Code:
hserin 100,noreceived,[wait("#"),str word_array\2]
Gives this error:
PICBASIC PRO(TM) Compiler 3.1.2.4, (c) 1997, 2019 ME Labs, Inc.
All Rights Reserved.
ERROR: Macro HSERINSTR?WL not found in macro file.

If array is byte size then is just fine. Is that correct? I could not find something in the manual.
