As a new user to Visual Basic, I am trying to use MSComm to communicate serially with a datlogger which i am trying to poll every second for data. I am getting VB 6.0 Pro tomorrow and should have no problems with the control itself as i do now with VB 5.0 However, do need help with setting the time intervals for polling the logger using MSComm and also if i can open both port on the same form if i wish to communicate with another piece of serailly linked equipment. Anyone?
