Does Python even run under MS-DOS?

Install an advanced OS, such as Debian ;-), then using the serial port
becomes rather simple.  You would only need to use the termios module
to set the properties of the RS232 protocol (7bit, 8bit, parity,
non-partiy, stop bit, etc) then use reguler file IO to read/write to
the serial port (/dev/ttyS0).
