Well, you certainly want to check out Device::SerialPort then. As I said
before, the interface mostly sucks, but it will be good enough for what
you want to do (send commands and receive data). I am just used to having
more control of the serial stream.
The constructor in this module works pretty much as you describe. I can
help you get up and running with it so you can cut out some development
time. Once you get used to it it's pretty easy to use.
Unix has a powerful but very complex interface to the serial port. There
are a couple good tutors online for accessing serial ports in Unix, but I
haven't gotten around to hacking up a good library. I just don't have
that kind of patience anymore, though a better one is sorely needed for
Perl.
