Serial Port Not Transmitting To Devices?

i am working on a senior project, trying to get a serial interface to work
properly. we can use it fine from a regular pc using sp1 and a built-in
serial port. when we try to use the same exact setup on a laptop with a
usb-serial adapter and sp2, everything works as it should when hooking up to
hyperterminal (data sends fine, you see it on the screen), but when hooking
it up to the microcontroller it will no longer work AT ALL, nothing.
remember, all the port settings are exactly the same... speed, parity,
everything. we have tried two different serial adapters with no luck. could
this be a problem with sp2, or just a problem with the serial adapter? i
think it must be sp2... is there any way to get around it?
