picocom|minicom for BSD

[bobmc@bobmc.net]

Why picocom or minicom? Computers, terminals, modems, and printers
were once connected in a system using RS232 serial ports. That use-case is
obsolete and the Ports of minicom and picocom are unmaintained but there is
still a use-case. For example, in a factory, simple controllers, widely
placed, can be wired into a system computer via RS485.

I would like to use picocom with DragonFly. It is most simple to list the
RS232 with "ls -l /dev/tty*" and  "picocom /dev/tty.." something? I tried
several and got "operation not supported" using the root account.

I have a Asrock QC5000-ITX which has an on-board UART. I also have a
USB-RS232 (CH341). Using these devices on Linux presents no challenge.

Perhaps one or more settings in rc.d.serial need to be changed. Is there a
document somewhere that would help me understand the BSD details.
