Hi everyone,
 
I have  posted a very simple program using DDE programmation. I am reading and sending data to one chanel ( RS232 connection). However, I dont seem to be able to do the same with the second channel ( I have changed the number of channel and/or the name of the server  but no better ). ( both of my servers where open and both of my RS232 connection work fine ).
 
Any help would great,
 
Thanks,
 
David
