Any ideas as to why only the latter debug is successfully received when (2) are sent as follows:

start:
Pause 100

DEFINE DEBUG_REG PORTA
DEFINE DEBUG_BIT 0
DEFINE DEBUG_BAUD 2400
DEFINE DEBUG_MODE 1
Debug "A",#w2

Pause 100

DEFINE DEBUG_REG PORTB
DEFINE DEBUG_BIT 7
DEFINE DEBUG_BAUD 2400
DEFINE DEBUG_MODE 1
Debug "A",#w2
GoTo start

My In as follows:

DEFINE DEBUGIN_REG PORTB
DEFINE DEBUGIN_BIT 0
DEFINE DEBUG_BAUD 2400
DEFINE DEBUGIN_MODE 1
DebugIn [wait ("A"),#w2]

I added pauses to see if it helped, and changed the order of Port pins used but the last Debug (of any 2 used) is the only one that is viewable on a Serout LCD.
