You can't -- the serial ports in v440 are driven by a 16550A
equivalent type UART, which can't work in synchronous mode.
You will need an HDLC board.
In general, if the port if driven by the su driver (for 16550
look-a-like chips), it can't do sychronous mode working.
If the port if driven by the se driver (for 82532 look-a-like
chips), it should be able to do sychronous mode working.
