I mean any comunication between computer and device. Serial sends 8 bits
at a time too, just have to decode/encode it out

It hasn't caused me any problem in the many years I have used it.
BTW, the module uses a parallel port, and since these are becoming
difficult to find, I wrote another, unreleased, one that uses a serial
port (even an usb to serial adapter should work).
Of course I'm not (still) using it in production, so it's not as tested
as the one using the parallel port.
I looked on mine and while it doesn't have a port on the back, it does
have a header on the board. If intel had their way, there'd be not
floppy, parallel or serial ports on any new board :(. With a serial
port, the data stream could be brought out to parallel giving you 8 pins.
My implementation doesn't use the data stream, it just uses the control
pins of the serial port (RTS as rotate west output, DTR as rotate east
output and CTS as the pulse counter input).
