[Amforth] amForth 4.7 atmega328p (uno) hangs while entering simple colon or constant definitions

[Charles S. <sum...@gm...>]

Hi,
Just started working with amforth 4.7 on atmega328p on uno (rev3) board.
compile went ok. connection with minicom from linux went ok.
But when I try to enter definitions it hangs after the second word. I've
seen this with both colon and constant definitions.
here's some output:

(This is where it hangs)

I'll provide any other information as requested. TIA
