# Windows usAge: ./ubstest.py COM1 0xhexcodes|string|icarus

# sends the data sepcified to the USB device and waits
# for a reply then displays it
#
# the data can be:
# 0xhexcodes: e.g. 0x68656c6c6f20776f726c640a
# would send "hello world\n"
#
# string: e.g. sendsometext
#
# icarus: sends 2 known block payloads for an icarus device
# and shows the expected and actual answers if it's
# a working V3 icarus
