I have been experimenting with basic example in the directnet manual (reads the status of x inputs of a DL06) in VB. I am using a serial port monitor to watch serial port activity as I am sending my inquiry and header info and i see the correct response from the DL06 in the serial monitor (4E 21 06 followed by 06 02 "data " 17,LRC and finally 04). So it seems that my "sending and receving is going ok, but I cannot seem to display the hex data in VB using MSCOMM. ARRRGHHH!!! Could someone post or send there code inregards to mscomm settings and formatting of the recieved hex data?

Look at the InputMode property and make sure it is 1 for binary. The data you receive in will have to be picked apart to look at each character. You may see a string of length xx but it will look like junk until you loop through each character and get its ascii value.
DN$ = MSComm1.input
For I = 1 To Len(DN$)
OneHexVal = (Asc(Mid(DN$, I, 1)))
Next I
