comment List serial devices on FreeBSD
@JdeBP With the manual, I've checked dmesg and it reports a single uart0 device. in /boot/device.hints, two UART interfaces are hinted, but they're both "at isa", which is a little odd to me, as one is on-board, the other is on PCI. Furthermore, dmesg reports pci5: <simple comms> at device 8.0 (no driver attached) I guess that would be the modem, but how can I attach a driver to that?

comment How did this '&' at the end of my command, make the script SO fast?
I suggest you read your shell manual. & makes the command run in the background, that's all. It didn't make it faster or anything. Read whatever shell's you're using (I assume bash) manual.
