need help to set up a serial link

[kinsiro]

hi, i m doing my fyp title serial link communication, now i m using pic16f84 as my controller, i connect my pic to RS232(MAX232CPE-the chip i use), then connect it to computer. now i m using the command as following

__________________________________________________ ______________

Include "modedefs.bas" 'to enable the mode option for n9600

trisa = %00010
TRISB = %00000000

symbol sec = 1000

d0 var byte
s_out var porta.0 'set pin no as output pin
s_in var porta.1 'set pin no as input pin
led var portb.4

loop:
Serin s_in, n9600, 1000, no_data, ("x"), [d0]
serout s_out, n9600, [d0]

goto loop

no_data:
high led
pause sec
goto loop

end

cannot oh.. the compile process is fail.. it stated error line-bad expression.. error line-expected '('
why will it like this?

Tried compiling the program and got the same errors. What do you want the program to do and what commands are you sending to the pic.

Ahem... people!!!!

The compiler is telling you what the problem is... let's all go back and read the MANUAL as to the correct SYNTAX for SERIN...

Not this...

Serin s_in, T9600, 1000, no_data, ("x"), [d0]

...but this...

Serin s_in, T9600, 1000, no_data, ["x"], d0

There's even an example in the book - read it!

Hi Melanie still new to all this serial stuff myself, I just thought I would try to help some with the limited knowledge I have gained. By the way what part of the world are you from.

[Melanie]

I'm pretty cosmopolitan actually, but for the last few years London England (hub of the Universe) is my home.
