What are the settings for the serial port with hyper-terminal? 9600, 8, N, 1?
If so the 84 should work. If "E"ven then try 8276.

The code you posted has the wrong baud. But lets start over, sort of.

With the VDIP connected to the PC as you had it just sen a couple simple commands to the VDIP with the PIC and see if the PC will display the return.
The below should cause the VDIP to diplay on the terminal a
D:\>
every 1.5 seconds..
At least it is here...
Code:
VinRXD  VAR PORTD.7 'DATA TO VDIP PIN #8 OM VDIP1
FLOWIN  VAR PORTD.6 'FLOW CONTROL FROM VDIP PIN #9 ON VDIP1

START:
HIGH PORTD.2  'LED
PAUSE 250
LOW PORTD.2
PAUSE 250
SEROUT2 VinRXD,84,["ECS",13] '9600 TRUE
HIGH VinRXD
PAUSEUS 10
SEROUT2 VinRXD,84,["IPA",13]
HIGH VinRXD
PAUSEUS 10
WAIT111:
IF FLOWIN = 1 THEN WAIT111
PAUSE 1000
GOTO START
