Found some info on WBs connect and why a lower baud rate was better. It depend on the host.
Due to the fast moving pace of the WarBirds flight environment, we are sending and requesting data more frequently than other Web programs that are able to wait before updating their information. WarBirds only requires a 19200 baud connection, but it needs to be a smooth one with few interruptions. Even with a 28800 baud modem with all the hardware compression, data compression, and buffer action enabled, unless you have a "perfect" connection, there will be a few errors and pauses due to the volume of traffic.
You can try to improve your connection by dropping the modem's connect speed to a lower setting. If dropping the speed isn't enough, you can try turning off hardware and software compression, or lowering your modem buffers.
There is even more detailed info, ive just got to find it.
Dog out.......
