Issac,
     The problem is going to be in the configuration of the 16f877a.=20
There is no activity on the en or the r/s pins. Argh! I thought that=20
this might be the problem. The clock is running. I have every reason to=20
believe that the pins are not set for digital I/O. Here is the setup=20
statements:
         TRISD =3D 0;
         TRISA =3D 0;
         ADCON0 =3D 0;
         ADCON1 =3D 0;
         CMCON =3D 0;
Any more thoughts on this?
Thanks,
rich!
