How Do I Get Packets To Show On My Terminal Window?

How Do I Get Packets To Show On My Terminal Window?

[Robert L Cochran]

Hello,

I'm a new ham and I'm trying to set up packet radio on Linux. I have a
Kenwood TR-7950 connected to a new KPC-3 Plus. After 2 attempts at
resoldering the radio port cable to the connectors, I now beleive the
KPC-3 is recieving packets because I can see the 'Rcv' light turn on now
and then, sometimes for long periods. It goes on and off and seems very
active.

I am using Red Hat 8. Connected to the KPC-3 Plus using minicom. I have
a 'cmd:' prompt on my minicom window, and the KPC-3 responds to my
commands. MONITOR is on. ABAUD is set to 9600. The KPC-3 has my call
sign in it (KB3JCM).

My problem is, when the KPC-3 recieves packets (as evidenced by the lit
Rcv LED) the packets do not show up on my Minicom terminal window. I'm
anxious to see packets at last!

Can anyone help me solve this problem? Is there a minicom setting I need
to invoke?

Thanks a lot!

73,

Bob Cochran

Minicom should be configured for 9600 8N1 connection, and if you
are seeing the cmd: and when you hit 'enter' it take you to a new
line with another cmd: prompt then Minicom should be configured okay.

(the first two are optional)

cmd: RESET
cmd: MYCALL KB3JCM
cmd: MONITOR ON
cmd: MCon OFF
cmd: MCom ON
cmd: MResp ON

...wait some time...

cmd: MHeard L

If you are still having problem, check the HBaud is 1200, and CD is INTERNAL.

I hope this helps,

I am using red hat 7.2 and kernel 2.4.18 with DXSpider.  I use the listen 
command to see what is going on with the TNC...  Within a new terminal 
window and to see both received and transmitted packet: listen -ap 
<portname> 

Hopefully this will help...

The 'listen' command will work wonderfully if your TNC is in KISS mode,
like yours and mine is, but Robert's TNC appears to be in TERMINAL or NEWUSER
(a limited subset of the commands in TERMINAL) mode.

Of course, I think Robert should take baby steps and make sure things
are working with his computer and TNC setup in TERMINAL mode before
trying to setup a AX25 station using KISS mode, IMHO.

I'm out of ideas as to why things aren't working, assuming that Robert
checked that his HBAUD setting is 1200 (not 300), and that the Carrier
Detect ('CD') is INTERNAL (or SOFTWARE, but INTERNAL is default afaik).
Does 'MHeard' suggest that the TNC is decoding any packets? Does listening
to the audio from the transceiver sound loud and "squaky" rather than
quiet hissing like? 


Cheers,
