help! SoftwareSerial won't work on higher pins.

I'm working with an Ard-Mega and SoftwareSerial doesn't seem to work on pins above 13 -- or am I imagining it ?

I need to drive 14 lcd's and a ps2 kybd -- I can't fit all those into the pins 2-13. Pins 0&1 are problematic as I need to retain communication with the IDE.

I can't use the NewSoftSerial as it's not compatible with the Mega yet.

Am I stuck ?

thanks

So, why not move the LCDs to the higher pins?

14 LCDs?

The Mega has 4 hardware serial ports. Why do you need to use software serial ports?

we tried moving them to the higher pins and they didn't work there -- didn't expect that

we are trying the hardware TX pins today (14,16,18) and hope to squeak by with those !

we are using the SparkFunSerLCD library I wrote a few years back and it's based on SoftwareSerial

I don't have the Mega here -- I'm coding/testing on a 168 and the code is running on the Mega in another state.

thanks
