Hi Gus!
Yep, many of fine features was done in few Deutschland BBS s/w,
they were always one step ahead...
For example, in most of DL bbs s/w was many years ago done of binary-file attachment
to message without use of any extra encoding/decoding, like 7plus, UUE etc.
But pity, its still not adopted in other world-popular BBSes like FBB/BPQ/NNA/JNOS etc.
73, Sergej.

Yes, the DPTNT is able to transport into a msg the *baggages*
too!
And automatically it decodes *anything* without any intervent
of Sysop :)
We are talking ante 2000... however JNOS2 implements UE/UUE,
and other...
Just to touch a very breaf explain... but there are books
to read and understand the matter... begin with a tipical
console session and illustrate the SID released:

_____________________________________________________________________________________
B. System Identifiers (SID)
A system identifier for forwarding systems is created with the following syntax:
[<system_name>-<version_number>-<command_set>]
The most important field is the <command_set>. The existing characters indicate
a protocol feature. They may be followed by a number, this indicates the protocol
revision.
Lets investigate DP's SID:
[DP-4.17-AB1D1FHMR$]
A = ACK messages known
B = huffman compression, only in conjunction with F
B1 = extended compressed protocol, resume and CRC added.
D = extended board names (8 chars), improved CRC
D1 = block crc mode in compressed forward
F = message exchange in blocks of 5, syntax of F6FBB
H = hierarchical addresses accepted
M = Message ID's accepted (BID's of private mails)
R = extended reject messages as defined by AA4RE
$ = Bulletin ID's accepted (I am really a BBS)
_____________________________________________________________________________________
C. The Forward Protocols
DPBOX uses seven different forward protocols
1) W0RLI
2) TheBox
3) F6FBB version 1
4) DPBOX version 1
5) F6FBB version 2 (resume mode)
6) DPBOX version 2 (resume mode)
7) DPBOX version 3 (as 6, additional block CRCs)
_____________________________________________________________________________________
As you all can see, also in this case the wheel and
other things are already invented: TNX German OMs!!!
