第一个报错是en2阻塞,这个是走以太网,与心跳无关(因为这里做的是串口心跳) 第二个报错是tty2串口心跳过载,TTY2属性: TTY tty2 TTY type tty TTY interface rs232 Description Asynchronous Terminal Status Available Location 01-S3-00-00 Parent adapter sa2 PORT number [0] + Enable LOGIN disable + BAUD rate [9600] + PARITY [none] + BITS per character [8] + Number of STOP BITS [1] + TIME before advancing to next port setting [0] +# TERMINAL type [dumb] FLOW CONTROL to be used [xon] + OPEN DISCIPLINE to be used [dtropen] + STTY attributes for RUN time [hupcl,cread,brkint,icrnl,opost,tab3,onlcr,isig,icanon,echo,echoe,echok,ec> + STTY attributes for LOGIN [hupcl,cread,echoe,cs8] LOGGER name [] STATUS of device at BOOT time [available] + REMOTE reboot ENABLE no + REMOTE reboot STRING [#@reb@#] TRANSMIT buffer count [16] +# RECEIVE trigger level [1] +# STREAMS modules to be pushed at OPEN time [ldterm] + INPUT map file [none] + OUTPUT map file [none] + CODESET map file [sbcs] +
红色部分那个FLOW CFLOW CONTROL to be used 流控制 属性的几个值分别代表什么意思?
