Correct. You can put the TNC in converse mode and construct a payload "by 
hand", but you cannot construct the header you will need for acting as a 
digipeater. You can set the "FROM" callsign. You can set the "TO" callsign. 
You can set the list of digis (the "UNPROTO" string). But you can't set the 
"digipeated" bit of any of the digis in the unproto string. These are the 
bits that are represented by an asterisk in the ASCII version the TNC shows. 
Putting an asterisk in the UNPROTO string will not have the same effect.
