Most places seem to recommend ZTerm for use with the Arduino when on OS X (I'm running 10.5) but it seems like ZTerm has been kinda stale for some time, and rather not fork over $ for A) a dead product and B) for working on OS hardware :)

I was wondering if anyone used anything else. I am not fearful of running any X11 apps or even console apps... I just want something good and open source!

I used "minicom", one of the standard open source unix things.  I think it's a standard part of the developer tool or maybe the X11 install?  Mine lives in /sw/bin, and I don't recall having to install it manually.
It works fine.

I think /sw is the root of the fink installation tree.  It's not on my mac, and I have the developer stuff loaded.

I'm a dinosaur - I still use kermit.  It was good enough for the Commodore 64...

Could be; I do have some fink stuff installed.  It was part of the "work" linux distribution that I had used recently, so it seemed natural to use it on macos as well..

Kermit brings back memories;    Did you find macos-ready kermit, or did you have to modify/build it?

I do have minicom installed, so I'll give that a whirl... good call :) as for kermit.. wow that brings back memories, not all fond ;) but I'll spark that one up too and see which one I like better.

I found a python serial modual which gives me all sorts of scripting capabilities that I didn't think of before, I'll report back if I have any success.

(ps, my arduino is shipping right now)

Got a standalone binary from somewhere, but it's been so long I don't recall where.

Its available via macports and probably fink as well.

I use screen.  

screen /dev/tty.<whatever> <baud rate>

ctrl-a k to quit.

You can also easily do serial I/O from perl on the Mac. I have been logging some data from my Arduino with the code below. I based it heavily on a snippet I Googled...

Code: [Select]

#!/usr/bin/perl
use Device::SerialPort 0.12;

$LOGDIR    = "/Users/peterl/Projects";              # path to data file
$LOGFILE   = "plant.log";            # file name to output to
$PORT      = "/dev/tty.usbserial-A20e1evB";          # port to watch

# Serial Settings#
$ob = Device::SerialPort->new ($PORT) || die "Can't Open $PORT: $!";
$ob->baudrate(9600)   || die "failed setting baudrate";
$ob->parity("none")    || die "failed setting parity";
$ob->databits(8)       || die "failed setting databits";
$ob->handshake("none") || die "failed setting handshake";
$ob->write_settings    || die "no settings";

# Send a string to the port
$pass=$ob->write("AT");
sleep 1;

# open the logfile, and Port

open(LOG,">>${LOGDIR}/${LOGFILE}")
   ||die "can't open smdr file $LOGDIR/$LOGFILE for append: $SUB $!\n";

open(DEV, "<$PORT")
   || die "Cannot open $PORT: $_";

select(LOG), $| = 1;      # set nonbufferd mode

# Loop forver, logging data to the log file
while($_ = <DEV>){        # print input device to file
     $theTime = `date`;
     chomp($theTime);
   print LOG $theTime . " - " . $_;
}

undef $ob;
