Atmega 128 Programmer

Can't Post

I have a Atmega 128 with programmer (W-PROG-816-5V). I want to know which cable I need to connect the programmer to my lpt port. I have a modem calbe (25-pin male to 25-pin female) with a gender changer on the female end. I connect the 25-pin male to the lpt port and I connect the 25-pin gender changer to the programmer. The Atmega 128 shunt is set to prog. I use Jeepers 2.1 with program NAwapoM1.2, Netowrk Dish and Board ATmega128@18,000MHz. If I click on Atmel, then Atmega128, then Erase Flash/EEPROM to test it, I get a message "failed to enter program mode". If I disconnect the cable completely from the PC, I get the same message. I think I might have the wrong cable. When I call the company about it, they tell me use a straight-thru cable. I think the modem cable is straight-thru (it is not a NULL-MODEM cable). Can anyone shed some light.
Thanks,
