Signmetics makes a DUAL UART in a 40 pin (also 28 and 24 pin packages)
called the 2681.  A MC68000 bus interface version is called the 68681.
They work very nicely, have on chip baud rate generator, 3 char incoming
buffer.  The smaller packages leave out most modem control pins, you
basically just get transmit and receive for both channels.
The 68681 is also available from Motorola.
