dty? cu?

[Andrew Ball]

Hello,

I'm new to Linux. I just plugged a USB->RS232 serial adaptor
into my aging Apple iBook with YDL and with the help of
dmesg found out that it became ttyUSB0.  I see that in /dev
but I don't see a corresponding dtyUSB0 to use for outgoing
connections.  I also can't find "cu", which is what I'm
accustomed to using to connect to serial things.  Can I add
this as a package?

Thanks,
