Hi Kelley,

> ... searching for settings specific to this unit for ARISS work

I'm not familiar with the Kantronics syntax for typing commands but
see below for a general summary of the parameters you may find useful.

ARISS has a summary of hardware TNC and soundcard TNC operations
posted at:
2.pdf (careful, might line wrap this URL)

The list of parameters you will find useful but may need to adapt to
Kantronics syntax:

MYCALL - Your Callsign Default is NOCALL, but you want others to know
you are there.

DAYTIME - YYMMDDHHMM Used if you want to timestamp the packets you are

MONITOR ON - Displays all packets on the frequency

MALL ON - Displays all packets on the frequency (connected or

MCOM ON - Displays the AX.25 protocol with the message (might clutter
your screen)

MCON ON - Allow you to see all packets even when in CONVERS mode

MSTAMP ON - Monitored packets are timestamped

MRPT ON - Displays the entire digipeat path for the packets.

CONSTAMP ON - Connect and disconnect status messages are timestamped

HEADERLN ON - Header information is displayed on separate line from
message text

PASSALL ON - TNC will accept and display packets that have errors
(noise). Partial packets, even with errors, are often still readable
to the human eye.

PASSALL OFF - TNC will only accept and display packets that have
complete CRC.

CONVERS <enter> - Mode to type packet message from keyboard directly
to the TNC. Ctrl-C will exit CONVERS mode.

MHEARD <enter> - Displays your TNC's "heard" list (updated only when

UNPROTO CQ VIA ARISS - Most basic string for ARISS to copy, route, and
digipeat your packet
