Hi, I'm probably going this route in a week or so ( dynamically changing buad rate ), but just by glancing through your code it seems 'dangerous' to me. Why not the more 'careful' route there you : a) disable global irq b) diable uart irq's c) disable uart module d) reconfigure the uart module ( speed ) e) enable uart module f) enable uart irq's g) enable global irq That should work, changing speed or other configuration while running seems to have to many unknowns to me. /Tony Tony K=FCbek, Flintab AB = =B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2= =B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2= =B2=B2=B2=B2=B2=B2=B2=B2=B2=B2 E-mail: tony.kubek@flintab.com =B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2= =B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2=B2= =B2=B2=B2=B2=B2=B2=B2=B2=B2=B2 -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
