Serial connection
You can connect your SwissMicros calculator to your
computer using an USB (mini B) cable. A terminal
emulation utility on the computer side is used to talk to
the calculator. Here we cover how to establish proper
serial connection between a SwissMicros calculator and a
computer. Note that OS X has a built-in terminal emulation
utility called
«
screen
»
which does the job very well.
