Hi Alexander! :-)

 ASA> The "serialno" is "eight character hexadecimal
number" according to 
 ASA> the FTS-0009. Does that mean that spaces are not forbidden? I'm not 
 ASA> native speaker, but I'm pretty sure they are :-)
Maybe my version of FTS-0009 is outdated, but I don't think so.

"The serial number may be any eight character hexadecimal number,  as
long as it is unique - no two messages from a given system may have the
same serial number within a three years.  The manner in which this serial
number is generated is left to the implementor."

Note the use of "may be", not "should be". I do believe
it is valid to use something different.

Ciao
