When you use tcp_dissect_pdus, an argument is the length of the data to be decoded.
Unfortunately, in her case, the length can't be determined except by  
scanning the packet for a terminating character:

I am developing a packet dissector plugin for Wireshark. The packets
I am dissecting do not specify their length in their header, but
they are terminated by a special character (and can be a variable
length). Additionally, multiple complete packets of the protocol may
arrive in one tcp segment. I would like to know how to tell
wireshark to divide up these packets. I understand there is a
command called tcp_dissect_pdus(), but I believe it needs the length
specified in the header. Is this correct?
so she can't use tcp_dissect_pdus().
