BS2SX Maximum Speed for serial communications

I want to built a dmx512 (lighting control) interface.
Getting RS-485 levels is no problem, there are several chips available that will handle that, but I am wondering if the Stamp is fast enough.
DMX is RS-485 and runs at 250,000 bps.
Will the BS2SX (or any stamp) be quick enough to handle this, or do I need more horsepower like the SX micro or Propellor ?
For ease of development I would prefer not to use assembly if at all possible, but any other high level language is fine.
Thanks

Don't visit my new website...
How does the Stamp or SX chip compare to a single processor on the propeller speed ways ??
If the stamp is the same or faster, then this should be doable on a stamp.
·· The Propeller can do over 400Kbps in one COG serially...However the BASIC Stamp wouldn't be able to reach the 250Kbps required for DMX.· I am unsure if anyone has attempted this with an SX or not.· You could post that question in the SX Forum or check SXLIST.COM for any VP that handles high-speed serial.
