SIemens is indicating taht they want encap cahracters to be D..data.. Iwould assume my resync character sholud be STX (X2) but an error occurs in testing :
invalid command name “resync:x2”
pdl is:
define phrase basic-msg;
; field data = variable-array( not(
)); ; end phrase;
/**********************************************************************
* End of declarative section, TCL management functions start here. *
**********************************************************************/
#{#
# This can be handled completely using the “basic” style.
hci_pd_msg_style basic phrase:basic-msg
field:data
resync:\x2
#}#

xb indicates hex b
maybe it needs to be indented.
Here’s where I got my info:

Robert,
This does not solve your issue but is Siemens saying what they propose is HL/7 MLP encapsulation? If so they are incorrect – what they propose looks like an abomination of async and HL/7-HLLP.
What YOU want is for them to conform to MLP.
By the way, is this for Soarian?

The error “invalid command name” makes this look like a whitespace/continuation problem. The interpreter is parsing out the “resync:” phrase as a command – not an argument to the hci_pd_msg_style command. Check to make sure that there is nothing except a carriage return after the “” on the line with “field:data”. I suggest deleting the lines with “field:” and “resync:” and retyping them. Or do away with the continuation completely and just have one line with all the arguments –
hci_pd_msg_style basic phrase:basic-msg field:data resync:\x2
That should eliminate the runtime error.
Now as to what should be the resync character – I agree with Jim that the vendor should be using the “tried and true” MLP characters.
