Hi, Vic......
Thanks much for the note. I have been using the minicom -s from the
root and have the manual for minicom. As you said, when it first came
up, it have the modem as the default, but I changed it to /dev/ttyS0 and
now, with Craig's echo command, I can see the Kantronics banner heading
in minicom.
My immediate worry is testing Xastir with the Garmin Rinos today --
tomorrow, I will work on Xastir and the Kantronics TNC again.
Thanks for your help and interest..... It is really nice to find such a
helpful community of people.
Later......... jt

You have to set minicom to the baud rate your using, the serial port your using and some other parameters. Yes there is a way to check the settings. type minicom -s return and you should see the present settings for everythin.
