minicom...

one of the beauties of nix is that it is device intensive, meaning, the operating system is hardware savvy...

windows often needs driver support when a device is added...

for a usb serial adapter to support the nix, ie, all that is required is the nix be told what device it is...

in this case it is USB0... discovering that is easy with grep (globally replace)

arteq@b:~$ sudo dmesg | grep  tty
[sudo] password for arteq:
[    0.000000] console [tty0] enabled
[    0.718578] tty ttyS4: hash matches
[    7.306285] fbcon: Remapping primary device, fb1, to tty 1-63
[    9.052698] usb 4-1: MCT U232 converter now attached to ttyUSB0
arteq@b:~$sudo minicom



at first it thinks you are trying to initialize a modem, that's why the  AT command error but...

there are a couple of setup steps for the serial port, which you can find here...
