As with many other such issues, instant cross-platformability
is likely to be rare. I admin I haven't looked at pySerial
but I imagine that, behind the scenes, it's doing some sort
of conditional imports according to platform. I imagine you'd
have to do something similar to get a list of port names.

On Windows, WMI can give you what you want. Look at the
Win32_SerialPort class. Hopefully, someone else can help
for other platforms.
