- Subject: Errors in TNC2 firmware???
- To: ham-digital@ucsd.edu
-
- I have recently been experimenting with TNC2 clones and had run
- across two peculiar "bugs" in the firmware of an MFJ 1278, and
- a tiny TNC2.
-
- The first problem relates to when the TNC2 sends to the computer
- the "Change incoming stream" command ("|B" to switch to stream B,
- for example). It seems that when in command mode, the TNC set the
- output stream to be equal to the input stream whenever it sends
- the "cmd:" prompt (if, of course. the output stream was set to
- something else previously). So it you are in command mode in stream
- A, and send a "|b" to set the input stream to B, and press Enter,
- the tnc will respond with "|Bcmd:" to tell that the output stream
- should now ALSO be set to stream B. The problem is this: The stream
- switch is sent JUST before sending the cmd: prompt. So if you are on
- stream A in command mode, and type "|bcst<CR>" to set the input to
- stream B and get the status of all streams, the tnc will send the
- results, THEN the |B, then the new cmd: prompt. SO, the output of
- the cst request made on stream B will be sent to stream A. In fact,
- the results will show that the input stream is B, while the output
- stream is A! Of course, if you type another "cst<CR>", the results
- will be sent to the proper stream, because it has already been
- corrected. Do all TNC2's exhibit this feature?
-
- The second problem is more major. I seems that when I am connected
- on two streams, and send text out on the first stream, and then
- switch to the second and do nothing, all output from the tnc is
- halted. For example, if I am connected on stream A and B to two
- bbs's, and I am currently on stream A, and I send "l<CR>|B" to list
- all files on the first bbs and then switch my input to the second
- bbs, the tnc will halt all output back to me. The results of the
- list command will come back to the tnc, and the tnc will receive them
- all internally, but will not send them to the computer....UNTIL I
- sent something to the tnc first. (Usually I send "^ck<CR>" to enter
- and then leave command mode. This will then allow all buffered data
- to be sent to me. However, it you do not send anything to the tnc,
- it will send nothing to you.
-
- I have found these problems by using paKet 5.1. PaKet creates
- a different window for each of the tnc's streams, and pressing a
- shifted arrow key allows you to switch between the streams. When you
- do this, paKet sends a "|" and the stream identifier. Therefore, it
- is very easy to switch to another stream to view incoming data,
- without wanting to send anything, thus causing the second problem.
- And having entering a command in one window and having the output
- return in another window (the first problem) was also easily
- spotted. I have reproduced these problems using a simple terminal,
- so they are not errors with paKet.
-
- One other note. I have also played with some Kantronics Tnc. They
- do not appear to have the lockup problem, but have an even worse
- version of the first bug. The incoming stream sent from the Kan TNC's
- is only changed when data comes in from over the air, not from
- commands. So if I am on stream A, and switch to stream B, SEND a
- <CR>, (this would fix the TNC2 problem), and start sending commands,
- the tnc never send me the stream switch command, so all the feedback
- from my commands always goes to stream A, (or whatever the last
- stream to receive over the air was). This is very frustrating when
- using paKet!
-
- Anyone have any comments on any of this? Has anyone else experienced
- this? Any ideas for solutions?

- Release Notes - IM/Mac 1.0=A727y
-
- - The numbers in the option-about dialog are now correctly formatted =
- for all
- languages.
-
- - Beachball cursor stops spinning immediately after finishing updatin=
- g mail file
- when quitting.
-
- - Beachball cursor stops spinning when a system error occurs.
-
- - When a system error occurs, the dialog that shows has a 'MacsBug' b=
- utton when
- MacsBug is running. This will create a file called 'crash_log' whic=
- h you need
- to send me.
-
- - Files with filetype 'ZSYS' and creator 'MACS' (e.g., 'VM Storage') =
- can no
- longer be send. They're treated as invisible files like the Finder =
- does.
-
- - When selecting a file to send, the text inside the outlined button =
- was 'Send'
- instead of 'Open' if the target was an alias to a folder.
-
- - When the last item (Record) in the "Edit 'bm.rc'=C9" dialog contain=
- ed only a
- filename, a system error occured. The syntax for that line is as fo=
- llows:
- [[[:<volume>:]<folder>:]<file>]. Square brackets enclose optional ite=
- ms.
-
- Examples:
- :My Hard Disk:My TCP/IP Folder:spool:Archive:Sent Mail
- spool:archive:sent mail
- archive
-
- - Finding out if MacsBug is installed via Gestalt doesn't work. Used =
- another
- method.
-
- - Sending a file that needs to be BinHex encoded will have its name t=
- runcated to
- 27 characters to make room for the '.HQX' suffix in the subject tit=
- le. The
- original file name will reappear after the BinHex decoding takes pl=
- ace at the
- receiver's end.
-
- - Deleted mail icon was 1 pixel too high.
-
- - Does stuff/unstuff of files on system 7 Macintoshes that have 'Stuf=
- fIt
- Engine=AA' (version 3.0 and higher) in the Extensions folder. Files=
- that were
- compressed/made with StuffIt, Compact Pro, AppleLink, DiskDoubler o=
- r
- UpdateMaker won't stuff twice.
-
- - Beachball cursor kept spinning when a system error occured during B=
- inHex
- encoding.

- PS (by PA2AGA)
-
- This version obsoletes all versions of info-mac/comm/radio-immac in t=
- he
- Sumex-Aim archives.
-
- The new IM/Mac has (hopefully) been uploaded to ftp.std.com, to the
- directory pub/hamradio/incoming, and to ucsd.edu, to the directory
- /hamradio/packet/tcpip/incoming. If it's not there (anymore),
- then look at /hamradio/packet/tcpip/mac.
