Nope, the leading characters are ascii for MS (message starts with MSH etc). So it’s just a case of missing start byte (and a completely different stop byte then the 1c0d which is mllp-standard).

So the message reads:

data

<lf><null>

and should be:

<vt>

data

<fs><cr>

I’m in contact with the developer of the pumps/docking to change their output, but I’m afraid this can take quite a while…

Hi Jim,

 

Thanks for your input. It took a while, but yes, we did start out with a pdl. And I got the hex dump. The raw message has no start byte (starts with <4d53>, and ends with <0a00>). We defined a pdl loosely based on the mlp-pdl, as follows:

define phrase basic-msg;

field data = variable-array( not( <lf> ) );

<lf><null>

end phrase;

but no luck here. Is there anything I’m missing here?

Thanks again!
