bash script for com port 1

[andybt]

Hi Guys,

I'm running Fedora core 6 and have iinstalled WINE to run a weather program. The program collects data from a weather station connected to serial com port 1. In order to get the program to "speak" to the com port I currently have to open the terminal window, log in as su and then chmod 777 /dev/ttyS0. I would like to be able to write a script that will run when linux starts to a) carry out the above chmod to the com port, and b) start wine and the program I need running at the same time. I am sure this is fairly easily done but have no idea where to start.

Any clues would be appreciated!!

Use sudo rather than su. Set up a line in /etc/sudoers (using visudo) to allow you to execute the command, then:

sudo chmod 777 /dev/tty/S0

(Though you should set things up so you can get by with less than 777, probably 774 would work.)

I would like to be able to write a script that will run when linux starts to a) carry out the above chmod to the com port, and b) start wine and the program I need running at the same time. I am sure this is fairly easily done but have no idea where to start.

Have you read the wine man page?

Thanks for that I'll give it a go.

Haven't had time to read the Wine FAQ's yet as I was more concerned with getting the com port working on each reboot. As I said I'm sure it's easy to do.

welcome to the forum

> a) carry out the above chmod to the com port

put "chmod 777 /dev/ttyS0" in /etc/rc.local: it will be
executed on bootup

> b) start wine and the program I need running at the same time

well, look at "man wine" see if there'e an option "-e"
or something, that let's you start wine with your
program already loaded

exec wine -e program
