There are a couple different serial-port wrapper packages that
make it easier to do serial port stuff.  Under Unix, access to
the serial port is exactly the same as when you use C:
open/ioctl/tcgetattr/read/write.  I've written a serial port
class for Posix serial ports.  It's at 

  ftp://ftp.visi.com/users/grante/python/PosixSerial.py

Using the Win32all package from ActiveState.com, you can access
a Win32 serial port using standard Win32 semantics (there are
examples in the Win32all package). There is also a Win32 serial
port package somewhere, but the last time I tried to find it I
couldn't.

Somebody recently wrote a cross-platform serial package that
has the same semantics under Unix and Win32.  I don't have a
reference, but if you search comp.lang.pythong for subjects
containing "serial" you'll probably find it.
