There is no software limitation on the baud rate with the Windows API although some software (Hyperterminal springs to mind) will only function with standard rates. For an odd baud rate a USB/Serial converter implemented as a virtual com port along with some suitably chosen software is a simple solution. The Equipment referred to in the original post connects to the monitoring PC using a USB link. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
