cfsetospeed - Sets the output baud rate for a terminal

cfsetospeed(): POSIX.1, XPG4, XPG4-UNIX
Refer to the standards(5) reference page for more information about industry standards and associated tags.
Points to a termios structure containing the output baud rate. Specifies the new output baud rate.
The cfsetospeed() function sets the output baud rate stored in the structure pointed to by the termios_p parameter to the speed specified by the speed parameter.
The zero baud rate, B0, is used to terminate the connection. If B0 is specified, the modem control lines are no longer asserted. Normally, this disconnects the line.
There is no effect on the baud rates set in the hardware or on modem control lines until a subsequent successful call is made to the tcsetattr() function on the same termios structure.
Upon successful completion, the cfsetospeed() function returns a value of 0 (zero). Otherwise, a value of -1 is returned.
