See the OS-9 Operating System User Manual, publication 1771-6.5.102,

for information on the scope and lifetime of

tmode and xmode changes.

Using the CC_VALCOMM Utility

Use the CC_VALCOMM utility to make xmode changes persist through

reset and power cycles. This utility validates the device descriptor that

was changed by the OS-9

xmode utility.

Syntax for the CC_VALCOMM utility is:

cc_valcomm {<opts>}

Function: Validate SCF descriptor for comm ports

Options: -comm=<num> Validate descriptor for comm port (0-3)

-comm=* Validate descriptor for all comm ports

The following example sequence sets the COMM1 port (/t1) for 19200

baud and hardware handshaking enabled .

$ xmode /t1 baud=19200 xon=0 xoff=0

$ cc_valcomm -comm=1

Hardware handshaking is enabled when the values for xoff/xon are

both 0. The changes persist through reset and power cycles.

Use the OS-9 device name as shown in the table below to reference the

serial ports.

The serial ports use a data-terminal equipment (DTE) setup. Pin 2 is

transmit out. Pin 3 is receive in. Pin 7 is ground. See Appendix C for

information on cable connections.
