Ed,
Got it....Found the spec ! Thanks for the hint !
Hank
"The bytes in the data string can have any value. To prevent confusion with the
frame
sequences <DLE> <ID> and <DLE> <ETX>, every <DLE> byte in the data string is
preceded by an extra <DLE> byte ('stuffing'). These extra <DLE> bytes must be
added
('stuffed') before sending a packet and removed after receiving the packet."

Per your message : That would be the 'byte stuffing' inherent in TSIP packet
structure.
Packet 0X8F-AB is specified as being 17 bytes including the subcode ( 8F)
Do you mean that you cant depend on that packet always being 17 bytes ?
I'm getting 18 bytes only when the time has 16 seconds in it. ( the second
byte is duplicated )
If you cant depend on having a constant number of bytes ( as defined in the
spec ) , how do you then decode it ?
Thanks
Hank
