sms.pl - access sms_client via a web browser
Author: David Usherwood ([e-mail])

This is a very simple perl script which allows text messages to be
input and sent to multiple recipients. It reads the entries in 
/etc/smsrc and offers them up in a multi-select list.

Please be kind - this is my first Web-related perl script.

Installation

The script should just install in your cgi-bin directory, and be 
accessible as http://<yourserver>/cgi-bin/sms.pl .

It requires CGI.pm . If you have a fairly new perl (5.003 upwards),
all the perl stuff should be there.

But you will probably need to make some permission changes to 
your system. Again, I am not a Unix security guru, so there may
be a better way to do this.

sms.pl is run by your web server. Under Apache (which I used for 
testing), the sessions can be specified to run under a userid such
as (say) www . 
sms.pl runs sms_client. Thus sms_client needs to be executable by www.
But sms_client runs libmodem, and that needs access (read I assume) to
/etc/modems. Thus make that readable by www (directly or via a group).
Lastly, sms_client talks to the modem hardware - so whatever modem
you want to access must be read/write to www. On my system it is
/dev/ttyS1, ie COM2 to PC types like me.
Then it should work. If it doesn't, I am interested to know why.
And I can certainly envisage that the Web page itself could be greatly
improved...
And I am going to try to think up some sensible trapping of 
comms errors, too
