Subject: JNOS Control-Z EOF Mail Fix
To: tcp-group@ucsd.edu
The following message was passed to me by SV1RD. As it is a very
useful patch (we have already added it to our locally maintained
NOS code), I pass it to this group.

MSG # TR SIZE TO FROM @BBS DATE TITLE
45187 B$ 3222 TCPIP AA6ED ALLUS 931205 JNOS Control-Z EOF Mail Fix
Forwarding path: F6CNB K3WGF AA6ED
-------------------------------------------------
MailBox.C Control-Z End of Message Problem
-------------------------------------------------
One of the most persistant problems occurred while receiving AX.25
bulletins from AX.25 is the presence of the Control-Z character in
a position other than the first character on the line. Usually NOS
hangs until the session times out, and will refuse to receive new
mail until the defective message from AX.25 BBS gets deleted via his
'EXPIRE' housecleaning utility. The following fix looks for a CTLZ
anywhere on the line, and if it finds one, replaces it with the NULL
character, writes that line to the temporary file, and replaces the
string with a new line that only has CTLZ and NULL in it. Granted,
the search 'strlen(m->line)' is a little slow, and I could have used
a temporary integer variable in its place, but the code does work.
This modification was made to JNOS version 1.07b but could apply
to many other versions. I understand that later versions of JNOS
may have fixed the problem. The "printf" will notify me about a
fixed problem, and only shows up about 1-in-500 messages, but that
is enough to hang NOS for days!
MAILBOX.C <line 1580>
----------------------
/* this is the existing JNOS code */
tputs(MsgAborted);
del_list(cclist);
return 0;
}
/* This is where the new code is added */
/* aa6ed CTLZ not at m->line[0] fix Line 1428 */
if (strchr(m->line,CTLZ))
{
for (i=0; i < strlen(m->line) , m->line[i] != CTLZ ;i++);
if (i != 0)
{
m->line[i] = NULL;
fprintf(m->tfile,"%s\n",m->line);
m->line[0] = CTLZ;
m->line[1] = NULL;
printf("Fixed CTLZ on incomming mail.\n"); /* A Brag message */
}
} /* end of aa6ed fix */
/* Stock WG7J Code to check for CTLZ characters */
if(m->line[0] != CTLZ && stricmp(m->line, "/ex")) {
#ifdef RLINE
--------------------------------------------
I hope the above programming suggestions can be of use. I understand that
JNOS 1.10 has fixed the problem, but it required a complete rewrite of the
mailbox code. This fix is simple to implement.

Hi, I've got an old GLB PK1 that I wanted to convert to a KISS box.
I've been following the thread on KISS on here and wondered if anyone
has actually written a KISS implementation for the Z80, where everything is
done in software ala the orginal GLB PK1?

Subject: Network Restrictions (sort of Re: Germans)
To: tcp-group@ucsd.edu
There has been discussion here recently regarding restrictions imposed
upon use of packet networks.
The Radio Amateur Telecommunications Society's (RATS) attitude towards
packet networking is that the ideal is a transparent "data pipe". Data
comes in someplace and leaves someplace else, and what the data is (as
long as there are no legality problems) is irrelevant.
If passing a certain type of data results in network congestion then the
network needs improvement. We'd rather see effort go into improving
thinsgs instead of imposing restrictions.
(One possible exception is "prime time" forwarding of packet bulletins.
RATS agrees with the policy here in the NY/NJ/CT Tri-State area which
restricts bulletin forwarding to non-prime time hours.)
RATS also feels strongly that networking and user access cannot coexist on
the same frequencies. Networking should be done on protected "backbone"
frequencies, free of hidden transmitters at a very least, and using
exclusinve point-to-point links whenvever possible.
Perhaps the most coherent discussion of this approach to networking is
found in documents of NEDA, the NorthEast Digital Association.
While this is the view of RATS, we cannot and do not force this upon
users of the ROSE X.25 Packet Switch. When it comes to our attention
that ROSE-based networks are imposing use restrictions we try to suggest
network topology improvements which should lead towards unrestricted use
of ROSE Networks.
Several ROSE Switch networks are "home" to TCP/IP activity. RATS
encourages this use of ROSE Networks, and asks that any with suggestions
that could improve ROSE usability for IP please contact RATS with their
comments.
Tom Moulton, W2VY, is working on a ROSE application which will permit
ROSE Networks to transport unconnected UI frames. (Internally ROSE will
establish a VC, but externally this will appear as unconnected datagram
transport.) (Phil! Get up from the floor! Yes, RATS is working
towards smoother interoperability with TCP/IP, etc.)

For the last 6 months I have been developing a packet driver to build=
into
the kernel of Coherent 4.0, and I am now at the beta stage.
I am trying to minimise the load on the cpu, by using Kantronics tnc'=
s
running in host mode, my driver can handle 32 dual port tnc's if only
I could afford them !
The driver presents the packets to the system as if they were coming
=66rom individual modems on seperate serial ports, so although you co=
uld
have say one tnc on comms 1 with 8 packet connections, Coherent think=
s
it has 8 modems on comms 1 to comms 8 all active.
Adding the comms ports to the ttys file, means that any packet caller=
s
are automatically logged in as modems and have full access to the sys=
tem.
I have also written a shell, so that they think they are connected to
a standard packet bbs, with the exception that they also have accesss
to multi user games etc.
I would like to hear from anyone else who is interested in playing wi=
th
Coherent 4
