Welcome to Episode #148 of Linux in the Ham Shack! In this installment, your hosts discuss Art Bell and the radio of kooks everywhere, free newsletters, Linux terminal utilities, FreeDV, FlexRadio, loggers and a whole bunch more. Thanks for listening, and enjoy all the information we cram in your earholes.
They barely get the introductions done, and Richard is off on a tangent about the great hobo migration in Texas. All this just proves Larry Bushey of the Going Linux podcast is right: LHS rambles. More on this in a moment.
Larry Bushey says LHS rambles in episode 160 of the Going Linux podcast. You know, Larry, you're right. 🙂
Terminal emulation programs for Linux.
If you're interested in running packet radio with your Linux computer, you'll likely need a terminal emulation program to communicate with your terminal node controller(TNC). There are several Linux tools you can use:
setserial is a command-line program designed to set and/or report the configuration information associated with a serial port.
microcom is a very basic terminal emulation program. Tip: pressing Control-\ will access the menu.
minicom is a menu-driven communications program. It emulates ANSI and VT102 terminals, has a dialing directory and auto zmodem download.
At the command line, type "minicom -s" to begin configuration. The first time you run "minicom -s", you'll probably want to run it as root so you have write access to the configuration file.
The first serial port in Linux is called ttyS0.
Most things will work at 9600 baud, 8 data bits, no parity bit, and 1 stop bit.
Text based modem control program.
Runs in a terminal screen
It's useful for other serial port tasks, too.
Ctrl-A followed by W turns on line wrap, so you won't have long lines truncated.
Install on a Debian-based system by using "apt-get install minicom" or use Synaptic.
Press Ctrl-A then X to exit.
GTK Term is a terminal emulator written with GTK+.
Gets added to the launch menu during installation, but with the name "Serial Port Terminal", not "GTK Term".
Has a nice looking interface.
Easy access to the serial port settings.
CuteCom is another graphical terminal emulator, with split input and output screens.
Ilan Rabinovich, of the Southern California Linux Expo, SCALE, sent a voice mail asking that we play promotions for the event. Unfortunately, we're too late with releasing the LHS episodes to promote SCALE in time. We'll try to do better next year.
2012 is rolling along nicely and Linux in the Ham Shack is rolling along with it, bringing you new ways to use your computer with amateur radio, and sometimes just technology for fun (and maybe profit). This time around, the guys break into politics -- just slightly -- and get a few grievances of their chests. In the middle segment, Richard and Russ discuss terminal emulation, something a radio amateur might need for accessing modems built into rigs or running packet TNCs. Finally, our intrepid co-hosts open up the mail bag and respond to listener feedback. If you would like to contribute feedback, please do so by sending us e-mail at firstname.lastname@example.org or calling in on our voice line at +1-909-547-7469.
