[Help] Problem with 2nd Software Serial PIC12F675

[Roamir Williams]

Hi

Im trying code to comunicate a PIC12F675 with a GSM SIM800L, this is my first code:

 #chip 12F675, 4
 #option Explicit
 #include <SoftSerial.h>

  #DEFINE RELE      GPIO.0
  #DEFINE DEBUG_TXD GPIO.1
  #DEFINE CALL_INT  GPIO.2
  #DEFINE DEBUG_RXD GPIO.3
  #DEFINE GSM_RXD   GPIO.4
  #DEFINE GSM_TXD   GPIO.5

  DIR RELE      OUT
  DIR DEBUG_TXD OUT
  DIR CALL_INT  IN
  DIR DEBUG_RXD IN
  DIR GSM_RXD   IN
  DIR GSM_TXD   OUT

    #define SER1_BAUD 9600     ; baudrate must be defined
    #define SER1_TXPORT GPIO  ; I/O port (without .bit) must be defined
    #define SER1_TXPIN 1       ; portbit  must be defined
    #define SER1_RXPORT GPIO  ; I/O port (without .bit) must be defined
    #define SER1_RXPIN 3       ; portbit  must be defined

    #define SER2_BAUD 9600     ; baudrate must be defined
    #define SER2_TXPORT GPIO  ; I/O port (without .bit) must be defined
    #define SER2_TXPIN 5       ; portbit  must be defined
    #define SER2_RXPORT GPIO  ; I/O port (without .bit) must be defined
    #define SER2_RXPIN 4       ; portbit  must be defined

    wait 500 ms
    Ser1Print "Debug Port"  'send a text
    wait 500 ms
    Ser2Print "GSM Port"  'send a text

    END

The first Software Serial works fine but the Second Send Garbage, Anyone can help me?

Thanks for you Help.

No expert here ... but,

Does Ser2 work when Ser1 is not configured?
If you flip the serial ports from Ser2 to Ser1 does that work ?

I just looked at the ASM. Looks good comparing Ser1 to Ser2 routines. So, try the changes above as this will inform us.
