help with storeing incomming serial

[Nobody/Anonymous]

I have this:
#chip 12F683, 8 'mhz
#config INTRC_OSC_NOCLKOUT, MCLRE=off, WDT=off, bod=0ff

dir GPIO.1 out ;open
dir gpio.0 in ;rx

#define RecAHigh GPIO.0 off
#define RecALow GPIO.0 on
InitSer 1,r1200,1,8,1,none,invert
dim temp as string

main:
SerReceive 1, Temp
if temp = "1234" then opendoor

goto main

sub opendoor
set gpio.1 on
wait 2 s
set gpio.1 off
wait 10 s
end sub

but i get a error on compile that says "cannot store ser_byte in the string varible temp"

Why?

The SerReceive command reads a byte variable from the Serial Port
so the line SerReceive 1, Temp wont work as temp is defined to be a string.
SerReceive will only read a single incoming byte .

so how can i get it to store a string of 4 bytes?

a few things to know
String is a special array where you store the length in the first element  temp

to fill the array/string, I think you have to receive and put in each element
DIM  temp as string
……….
SerReceive 1, Temp(1)
SerReceive 1, Temp[(2)
SerReceive 1, Temp(3)
SerReceive 1, Temp(4)
Temp(0) = 4

I don't see a string compare in "lowlevel" string routines

So one at a time to check for valid "keycode"

      IF Temp(1) != "1" then goto main
     IF Temp(2) != "2" then goto main
     IF Temp(3) != "3" then goto main
     IF Temp(4) != "4" then goto main
opendoor

This is just to give some ideas how to do it.
