has anyone ever owned one of these and had issues with it who later solved those issues?

I have a generic adapter, complete with drivers, claims to be rs232 or whatever it is compatible (to the best of my knowledge my serial equilizer is rs232) as well as plug and play.

unfortunately, I cant get the two to talk together! my laptop doesnt have a serial out so I need to convert if I can! what could be causing the communication issues?

I have all devices set to com1, so I know the port routing is all correct. when I hit connect, my EQ program crashes.
