Hserout, multitasking?

[mister_e]

mmmm can't say you can do it elsewhere than in a interrupt handler routine... try TXSTA=0

OR do a loop to send your data byte/byte, do a test after each HSEROUT that say to continue or stop HSEROUT.

for SEndData = x to y
     Hserout [Myvar[SendData]]
     ' set your stop/continue flag here and after that
     ' 
     If ContinueOrStop = Stop then SendData = y ' to get out of the loop
next

TY for the info
