I developped a program to communicate on serial port com. It works fine on xp/W2000. Then I wanted to include this into a bigger project, so I decided to change it into a dll. It works fine on W2000, but the same application using the same dll NEVER works on WXP. Does anybody have an idea about what could happen? When I say it never works I mean that the thing that reiceives the data transferred on the serial link (I see the data transferred via a spy on the link) does'nt act as it really reiceived everything OK. I mean all the data are transferred, but it acts as if the flow was interrupted sometimes. THANKS for your help!!!!
