Yamaha DTXpress/DTXplorer/DTXtreme

Hi Guys.

Over the past few nights I have attempted in vain to connect my 
DTXPRESS to my laptop using the CCIBM Serial To-Host cable. For a 
rundown of my hardware here it is. I have a Dell Latitude CP-XJ 
running Windows 2000. The onboard sound card is an ESS Maestro.

I purchased the Serial To Host cable last week and expected that I 
would be able to connect the DTXPRESS to my notebook through the 
serial port. I dowloaded the Yamaha CBX drivers for this process but 
so far I have been unable to establish any communication between the 
two. Last night I downloaded the DTXCHANGE SysEx utility from 
DTXpressions but I did not establish any connection either.

When using Stickmaster I receive error messages of the following 
format:

"Cannot change the MIDI Device (output)"
Inside this software I cannot set my the Output device to be the 
Yamaha DVX A driver.  

Can anyone who has experience using the serial port to connect to the 
To Host port on the DTXpress please advise on these issues.
Many thanks in advance,
Brian
