  A standard PC 8250/16450/16550/etc serial port is indeed asynchronous, but
there are synchronous serial cards for ISA, PCI and PCMCIA (at very least).
Just Google "synchronous serial card".
 
  I've got a 11/53+ with a DSV11 card and a uVAX-III with a DPV11, and it'd
be fun to have something to connect them to :-)  [Yeah, I could connect them
to each other, but they're already on the same Ethernet...]
