Chris, as I said in last post I have a DELL 2.8 GHz, Pent.IV (XPS system) with 512 MB RAM. I have used the vi with both the standard RS-232 (COM2, up to 115.2 Kbaud) port and also the Sealevel USB to RS422 (COM5, up to 230.4 Kbaud)converter. With each COM, I was not able to get more than ~20 cycles/sec with the vi I sent.
Thanks for the help. Rob
