MCSPlus serial interface to EasyPIC6 not working?

[jellis00]

Am not able to get serial communication from MCSPlus with EasyPic6 while running program on 18F4550.
I set the SW6 and SW7 for RC7 & RC6 respectively per the User Manal and MCU data sheet for the EUSART in the 18F4550. I also made sure the host computer had the COM1 serial interface set to 9600 BPS, 8 data bits, no parity and one stop bit (8N1) .
The MCU was programmed using MCSPlus as the editor, PICBASICpro as the compiler, and MPASM as the assembler to create a .hex file, which was then burned into the MCU using a USB interface from PICFLASH to the EasyPIC6.
After programming I have then been trying to use ICD that is built into MCSPlus to step the source code and monitor variable values, which requires the serial interface connection between the MCSPlus host and the EasyPIC where the program is running in the PIC18F4550. I keep getting a serial interface timeout when I start the ICD in MCSPlus even though I have made sure the seral interface is defined in the code and the PC's serial settings have been set to match the MCSPlus settings of COM1.
Can you please advise from above info what I am doing wrong that is causing the serial interface to timeout without connection??

Does the easypic hava a level shifter (RS232) chip? If not you will need one using the PIC's USART.

And

with out seeing your configs and code we have no way of knowing if the chip is running at the speed you think it is.

Yes it has a MAX202 chip installed on the EASYPIC6 board.

Sorry about that...I see now I referenced my configs but forgot to include them. Here they are. One other relevant piceof info: the Easyic6 has a 8 MHz crystal installed for the MCU. I realize the DEFINE in the code must tell the compiler what the MCU clock is, and in this case I intend on this code using a USB interface, which is set by configs for the 48 MHz USB clock. Therefor the DEFINE to tell the MCU it is a 16 MHz MCU clock.
I have also tried both HYPERTERM and the USART Terminal that comes with mikroelectronica's EasyPic6 to see if the terminal makes a diference....they both never connect and timeout.
Would appreciate any advice you can give me.

DEFINE OSC 16

[mackrackit]

Try defining the OSC at 48.
I am not near my data sheets , on a phone, so I am not sure if you have the PLL correct. But if you do have it PLLed to 48 then that is what you set the define as.

I use the same chip with a 4 external and run it at 48.

DEFINE OSC 16 should work with your config settings. If you're trying to use the MCS+ ICD, make sure you compile with the ICD/Compile button. If you're just trying to verify the connection with HSEROUT, then use the normal Compile button.

[jellis00]

I tried both 48 and 16 MHz defines and also made sure the recompiles were with just the Compile button and not the Compile/ICD button.
I also generated a simpler program to test the serial inteerface that just reads the HSERIN from the PC host and then resends the same received character to the PC host with HSEROUT (see included code below). The PC host hyperterminal says the sends are going out, but never receive back any resends from the PIC. I also included in the HSERIN statement a timeout to a label that blinks LEDs as an error if timeout occurs. It does, so it confirms that the serial interface is not working and is timing out.
Almost seems like a hardware failure on the EasyPic6 side, but I don't want to RMA the EasyPic6 all the way back to Rumania to have them check/repair the unit due to the time delays and the cost....the EasyPic6 is my development board....just wish I could get the serial interface to it working so I could then use the MCSPlus ICD debugger with it.
At this point I am really baffled. Any other suggestions as to how I can verify the serial interface?
