Sure, the OOPic can send the string but with somewhat different
syntax. Probably something like:

Dim s as new oSerialPort

sub main()

s.baud = cv9600
s.operate = cvOn
s.value = "CONF:VOLT:DC0.5"
s.value = 13
s.value = 10

end sub

You might be able to concatenate the CR and LF to the first string but
I haven't tried it in a while.

Where you may have a problem is the fact that the oSerialPort only has
a 4 byte buffer. It is possible the instrument will send the data
faster than the OOPic can process it.
