Program (Windows Service) for sending and receiving of sms through gsm-modems or
mobilephones.
As in most projects, I faced many problems during the development-period of
SimpleXms. The worst problem was making the communication with the modem be
fast and responsive. This was solved by making multiple threads that
co-operated with each other.
At start I did not use Franson Serial Tools, but another RS232-component.
After "completing" the project, I discovered that there were rare cases of
total failure while communicating with the modem. My service did not crash,
but the communication just didn't work as it should. I spent about a week,
trying to find out which section of my program that was causing the error. I
could not find any code-section that was erroneous.
There was only one thing I hadn't checked, the RS232-component. I mailed the
programmer of the RS232-component, telling about my suspicion. I got a reply
with some code-lines of what I would call a "dirty-fix". I could never go to
bed at night knowing one of my programs have a "dirty-fix", but I wanted to
try the fix, only to see the result. The failure did not disappear. I mailed
him back, and he said he would look at it in the weekend.That's when I decided
to download Franson Serial Tools. After switching from
the old component to Franson Serial Tools, it was stress-tested for a
period. The rare cases of failure were history.
