I am using Jon Williams' functions for outputting characters via the serial port. I get bytes output correctly but not strings.

  TX_BYTE:	'Use: TX_BYTE outgoing byte
    'LET temp1 = __PARAM1	'Outgoing port
    LET temp2 = __PARAM1	'Outgoing byte

    SEROUT TX_DB9, Baud, temp2
    RETURN

  TX_STR:	'Use: TX_STR [string| label]
		'  "string" is an embedded literal string
                '  "label' is DATA statement for stored z-string
    temp3 = __PARAM2    'get string offset
    temp4 = __PARAM3    'Get string base
    DO
      READ temp4 + temp3, temp5	  'Read a char from the string into temp5
      IF temp5 = 0 THEN EXIT     'String complete
      TX_BYTE temp5
      INC temp3                   'Point to next char
      temp4 = temp4 + Z           'Update base on overflow
    LOOP
    RETURN

When I execute TX_STR "Start" here is what I get at the terminal
õ$B  ¤   ¤
           ¤
             õ$
B  ¤     ¤
           ¤
             õ$

Any ideas?
