I don't know which version of VB you use. If it is 5.0 or 6.0 it is very easy:
MSComm1.InputMode = 1
Dim bOutput(0 To 10) As Byte ' Output Binary Array
bOutput(0) = 0
bOutput(1) = 1
MSComm1.Output = bOutput
But if you use VB 4 or less, you'd better use API functions CreateFile(), ReadFile(), WriteFile().
Good Luck!
