How to read a serial data com port

[Luke]

I am getting "bad record length" error at the GET #1, ,m$ statement in the following QB64 code. I can't seem to find exactly how I should go about reading the message posted in the com port buffer by Arduino when all I asked for is A/D voltage on analog pin 4.
Any Ideas?
OPEN "Com3:9600,n,8,1,ds0,cs0,rs" FOR RANDOM AS #1
_DELAY .5 '                                       Delay to let Com Port settle
FIELD #1, 50 AS m$

t1 = TIMER '                                     Start time for getdata

getdata:
bytes% = LOC(1) '                             Check receive buffer for data
IF bytes% = 0 THEN GOTO getdata '         After thousands of getdata cycles it continues
PRINT "Bytes="; bytes '                            Bytes remain at 0
DO UNTIL EOF(1)
    GET #1, , m$ '                             BAD RECORD LENGTH ERROR
    PRINT "LEN(m$)= "; LEN(m$) '               Length of m$ = 10
    IF INSTR(m$, "*") > 0 THEN GOTO duh '    Never finds End of Message (*)
LOOP

IF bytes% = 0 THEN GOTO getdata
t2 = TIMER '                                         End time, Have data
DeltaT = t2 - t1 '                                   How long did it take?
GOTO stepover

duh:
PRINT "DUH instr= "; INSTR(m$, "*") '               Never hits this line
stepover:

tmp$ = "DeltaT= #.### Seconds Until LOC(1) > 0" '    Various times arround 0.66 Sec
PRINT USING tmp$; DeltaT
PRINT "m$ Received= "; m$ + "&" '                 Prints 10 spaces No Data
PRINT "endofdata= "; endofdata '                  endofdata=0, Never got "*"
PRINT "ctr= "; ctr, CHR$(13) '            Show number of times you pressed continue
CLOSE #1

Arduino Code sending info is the following:

 if ( cmd == 2)//getanalog
   {
        int sensorValue = analogRead(pin);//
        delay(10);
        float voltage= sensorValue*(5.0/1023.0);
        Serial.print("Voltage =");
        Serial.print(voltage);
        Serial.print(",");
        Serial.print("*");

The asterisk should be in the buffer indicating the end of my message.
