Command Input

PPCx-Diag>scc bauds
Description
This test transmits 256 characters at various baud rates. The data is
received and compared. If any protocol errors are created or the data is not
correct when received, the test failed.
The bauds tested are:
1200
2400
4800
Note
9600
19200
38400
Because of the design of the Z85230, when internal loopback
testing is performed, data is still transmitted out of the device on
the TxD line. This may cause problems with terminals, modem,
printers, and any other device attached.
