OWIN not jumping to label

I’m trying to get a OWOUTcommand to jump to a label when there is no sensor present. I have two ports on a 16F873a using 1-Wire to read DS2438 battery monitors. If there is no sensor present I want to jump to a label. I have verified that on an empty port, the master sends the reset pulse but there is no presents pulse. The program does not jump to a label as expected. On a port where there is a sensor the program works as it should. Am I setting up the command correctly to jump to a label if sensor is not present? There is no example of this in the manual. Comments Please! Thanks...

Code:

Sensor:
    OWOUT OWnet,1, [skiprom,WriteScratchpad,$00,$00],Senout
    OWOUT OWnet,1, [skiprom,ConvertT]    :pause 10
    OWOUT OWnet,1, [skipROM,ConvertV] :pause 5 
    OWOUT OWnet,1, [skipROM,RecallMemory, $00] ; Skip ROM search, Recall Memory
    OWOUT OWnet,1, [skipROM,ReadScratchpad, $00]  ; Skip ROM search, Read
    OWIN    OWnet,2, [STR DSbuffer\9]' Read 9 bytes
    Serout2 TX_485, 84,[" 1-Wire is present on main"]
    GOSUB GetT_V
Senout:
                RETURN 
ALT_Sensor:
    OWOUT OWalt,1, [skiprom,WriteScratchpad,$00,$00],Altout
    OWOUT OWalt,1, [skiprom,ConvertT] :pause 10
    OWOUT OWalt,1, [skipROM,ConvertV] :pause 5 
    OWOUT OWalt,1, [skipROM,RecallMemory, $00]
    OWOUT OWalt,1, [skipROM,ReadScratchpad, $00] ' Skip ROM search, Read
    OWIN  OWalt,2, [STR DSbuffer\9]' Read 9 bytes   
    Serout2 TX_485, 84,[" 1-Wire is present on Alternet"]
    GOSUB GetT_V
Altout:
              RETURN

I've checked the 1-wire presence with a different PIC and different 1-wire device, and it seems to be working ok.

I noticed the point that your program jumps to doesn't give any indication that it jumped there.
Maybe you could try something like this for testing purposes.

Code:

Sensor:
    OWOUT OWnet,1, [skiprom,WriteScratchpad,$00,$00],Senout
    OWOUT OWnet,1, [skiprom,ConvertT]    :pause 10
    OWOUT OWnet,1, [skipROM,ConvertV] :pause 5 
    OWOUT OWnet,1, [skipROM,RecallMemory, $00] ; Skip ROM search, Recall Memory
    OWOUT OWnet,1, [skipROM,ReadScratchpad, $00]  ; Skip ROM search, Read
    OWIN    OWnet,2, [STR DSbuffer\9]' Read 9 bytes
    Serout2 TX_485, 84,[" 1-Wire is present on main"]
    GOSUB GetT_V
RETURN

Senout:
    Serout2 TX_485, 84,[" 1-Wire presence NOT DETECTED!"]
RETURN

Thanks Darrel for taking the time to look at this. My indication of a jump or no jump was the Serout message. It there was a jump there would be no message on that port. The fact that you tested OK on another PIC tell me something, at least I have the OWOUTcommand set up right. I'll keep testing and post any new findings.
