1The support for multiple serial interfaces as implemented is mainly 2intended to allow for modem dial-in / dial-out while still being able 3to use a serial console on a (different) serial port. 4 5At the moment, the ports must be split on a SMC and a SCC port on a 68xx processor; other configurations are not (yet) supported. 7 8Support for hardware handshake has not been implemented yet (but is 9in the works). 10 11*) The default console depends on the keys pressed: 12 - SMC if keys not pressed (modem not enabled) 13 - SCC if keys pressed (modem enabled) 14 15*) The console can be switched to SCC by any of the following commands: 16 17 setenv stdout serial_scc 18 setenv stdin serial_scc 19 setenv stderr serial_scc 20 21*) The console can be switched to SMC by any of the following commands: 22 23 setenv stdout serial_smc 24 setenv stdin serial_smc 25 setenv stderr serial_smc 26 27*) If a file descriptor is set to "serial" then the current serial device 28will be used which, in turn, can be switched by above commands. 29 30*) The baudrate is the same for all serial devices. But it can be switched 31just after switching the console: 32 33 setenv sout serial_scc; setenv baudrate 38400 34 35After that press 'enter' at the SCC console. Note that baudrates <38400 36are not allowed on LWMON with watchdog enabled (see CFG_BAUDRATE_TABLE in 37include/configs/lwmon.h). 38
