string&i2c

hi all.
what i want to do is sending string from pc-hyperterminal via pic16f876 to i2c then reading i2c
my code is:
INCLUDE "MODEDEFS.BAS"
DEFINE CHAR_PACING 65000
DEFINE OSC 20
CONTROL CON $A0
DPIN VAR PORTC.4
CPIN VAR PORTC.3
VALUE VAR BYTE[21]
ADDRESS VAR BYTE

SERIN2 PORTC.7,396,[WAIT("Ee"),STR VALUE \ 21]

ADDRESS=0
WRITEX:

FOR ADDRESS=0 TO 20
I2CWRITE DPIN,CPIN,CONTROL,ADDRESS,[VALUE]
PAUSE 10
NEXT ADDRESS


READX:

FOR ADDRESS=0 TO 20

I2CREAD DPIN,CPIN,CONTROL,ADDRESS,[VALUE]
SEROUT2 PORTC.6,396,[#ADDRESS,"=",VALUE[ADDRESS],10,13]
NEXT ADDRESS
LOOP:
GOTO LOOP
END


when i send "EeABCDEFGHIJKLMNPRSTUV" to i2c
the response is:

Òú
1:B
2:C
3:D
4:E
5:F
6:G
7:H
8:I
9:J
10:K
11:L
12:M
13:N
14:P
15:R
16:S
17:T
18:U
19:V
20:
as you see the ,i can't read the first address and value(0=A),i don't understand why?

tank you

May be Your write Routine, test this:

WriteX
FOR ADDRESS=0 TO 20
I2CWRITE DPIN,CPIN,CONTROL,ADDRESS,VALUE[ADDRESS]
PAUSE 10
NEXT ADDRESS

@beto
tanks for quick response.
i've alredy tryed what you said.but the responce is

êú
1=B
2=C
3=D
4=E
5=F
6=G
7=H
8=I
9=J
10=K
11=L
12=M
13=N
14=P
15=R
16=S
17=T
18=U
19=V
20=

there is no change

You are using level shifters?, the problem then looks as voltage chirp, if you is using only resistors then try to set High the TX pin BEFORE Data transmition!

@beto
thanks again
i did it as you said
now the response is:

0=ÿ
1=B
2=C
3=D
4=E
5=F
6=G
7=H
8=I
9=J
10=K
11=L
12=M
13=N
14=P
15=R
16=S
17=T
18=U
19=V
20=

i can see first address but not correct value
