I just ran a loop increasing the communication speed of the LCD by 1 and then displaying the speed. When I was able to read the information on the LCD, that is the speed to use. It looks like something from $40E2 to $40F6 works. I need to do a little more testing to find out if there any differences in that range. I'm not sure if this the right way to go about solving this problem but it works......for now.
