Currently have WY55 and am replacing as the screen isn't too bright. I have all setup correct and the Modem pins are correct also (this information was taken off the old one). It hooks up to an old IBM PC III with Linux software package, for inventory control where I work.
I had thought it was plug and play but I must be missing something and there is no one to ask.
It comes on but I cannot log my password into the system. Hooked up the old one and it works fine, just very dim.
Please any suggestions as to where to start???
