Sorry for being a bit off topic, I am trying to communicate to a Visual Basic application using a pic, at first I thought it was my code (pic), but then when I tried to use a terminal program on another computer it didn't accept the input either. The cable should be fine, because I can communicate between two computers, in dos using a terminal program. Can anyone help me with this, any example code, I am trying to use the mscomm control to make my life simple but I must be missing something simple with the On_comm() event. BTW, I can send easily with the mscomm control. Thanks, Joe Hoffmann E-Mail jhoffman@it.sait.ab.ca
