[Today’s run: 6.8 miles]<\/p>\n
I recently picked up an old IBM notebook computer for use with my radio stuff.\u00a0 I was able to load a version of Linux on it (the free unix-like operating system) and it seems to be working pretty well.<\/p>\n
Today I worked on getting the serial port set up\u00a0 to talk to my GPSDO.\u00a0 The GPSDO writes out a message every 16 seconds.\u00a0 I’d like to gather those into log files and then do some statistics work on them.<\/p>\n
It has been quite a while since I have done much with serial ports from a linux box in a scripting environment (even longer for C programming).<\/p>\n
I got the serial port figured out using\u00a0 minicom, a terminal\/modem program.\u00a0 While that was working I ran ‘stty -g\u00a0 < \/dev\/ttySx > saved.stty’ on another window (for the right ‘x’ to match my serial port). That saves the serial port settings in a file.<\/p>\n
Then I got out of minicom.\u00a0 I ran ‘stty `cat saved.stty` < \/dev\/ttySx’\u00a0 which puts those settings back in place.\u00a0 Then I could run ‘cat \/dev\/ttySx’ and see the logging lines showing up on the screen.\u00a0 From there it was pretty easy to create a little script to write the logging to a file.\u00a0 I took the opportunity to add timestamps in UTC to every log line.<\/p>\n
I want to get the TRF logging program installed on this laptop, then I can use it for contest logging.\u00a0 I don’t think it has the horsepower to use for digital modes, but time will tell.<\/p>\n
