SMS Free Software Updated

There's nothing like customer problems to show up missing features or weaknesses in my SMSQ software. A driver was interfering with the GSM modem on one system, so I added "Monitoring Messages" that get sent out on a predefined basis, like every hour during the day. They were so punctual that I could almost set my watch using them, and they helped isolate the problem.
Then one of my largest customers had the SIM card for their GSM modem suspended by Autopage, their cell phone company. This effectively blocked the sending of 2000 appointment reminder messages the first day, and when it was repeated the second day 992 messages were blocked before we picked it up. Needless to say Autopage is a really popular supplier with this client right now.
Catching up the backlog of messages caused me to add a "start time" and "end time" to the package, to prevent messages being sent at rude times, like the early hours of the morning. I also added the ability to read the entire message that was being sent or received, which helps to ensure that the system is working correctly. SMSQ is freeware, and uses an Access database to store the messages.
