2 X 16 LCD will not show text
codes for backlight and cpu reset but every attempt to send normal text
fails. I can see the bits arriving at the LCD with a scope. I have
copied sample software from web site. All settings are default (9600,
reverse logic, etc). I am using pin 13 of the BX-24 to drive the LCD
and have checked voltage level at the LCD as 5.15 volts.
I have used the BX-24 with serial LCD's before (a parallax LCD,
actually) with no problems. Am I missing something here?
I assume you mean you see nothing on the LCD. Contrast?

PROBLEM SOLVED! It was caused by the contrast pot turned all the way
I can turn the backlight on and off as described in the manual and when I send a 'reset' command the lcd does reboot but when sending a text letter nothing happens. I have set contrast to 255 with no effect.
