By default, the baud rate is 64,000 bps on a synchronous serial interface.
The following are the baud rates available with synchronous serial interfaces:
1,200 bps, 2,400 bps, 4,800 bps, 9,600 bps, 19,200 bps, 38,400 bps, 56,000 bps,
57,600 bps, 64,000 bps, 72,000 bps, 115,200 bps, 128,000 bps, 192,000 bps,
256,000 bps, 384,000 bps, 512,000 bps, 1,024,000 bps, 2,048,000 bps, and
4,096,000 bps.
The baud rate range available with synchronous serial interfaces depends on the
applied physical electric specifications.
For V.24 DTE/DCE, the baud rate available ranges from 1,200 bps to 64,000
■
bps.
For V.35 DCE/DCE, X.21 DTE/DCE, EIA/TIA-449 DTE/DCE, and EIA-530
■
DTE/DCE, the baud rate available ranges from 1,200 bps to 4,096,000 bps.

CAUTION:
Take the physical electric specifications of the cable into consideration when
■
setting the baud rate for a serial interface.
The baud rate adopted by a DCE-DTE pair is determined by the DCE.
