You really need to get a logic probe or scope to do this kind of
work. Something like this: http://tinyurl.com/4pu7km
There are
several inexpensive versions on ebay but this one was "Buy Now".
The following code works in that the IOLine idles high (same as a
real TTL USART) and the bits go low. It is not necessary to define
the flow control which would, I suspect, be an output used only when
the serial port is used for input to throttle the sender.
Dim S As New oSerialL
Sub main()
ooPIC.Delay = 5000
S.IOLineS = 9
S.Operate = 1
Do
S.String = "hello"
ooPIC.Delay = 20
Loop
End Sub
I have not run the signal to a level shifter and on to Hyperterminal
but I'm pretty sure it's correct. Compiler V6 and chip B.2.2+
