今天在P630测试机上想用串口连接来重装一下系统。但配置好CRT后,如下:
就是连接不上,不知道怎么回事,请各位指点,谢谢。我在网上找了些资料查看串口状态,日志如下:
[630@root:/]#lsdev -C |grep tty
tty0 Available 01-S1-00-00 Asynchronous Terminal
tty1 Available 01-S2-00-00 Asynchronous Terminal
tty2 Available 01-S3-00-00 Asynchronous Terminal
[630@root:/]#penable

tty2
[630@root:/]#penable -a tty0
[630@root:/]#penable
console
tty1
tty2
[630@root:/]#stty -a
speed 9600 baud; 47 rows; 125 columns;
eucw 1:1:0:0, scrw 1:1:0:0:
intr = ^C; quit = ^; erase = ^H; kill = ^U; eof = ^D; eol = ^@
eol2 = ^@; start = ^Q; stop = ^S; susp = ^Z; dsusp = ^Y; reprint = ^R
discard = ^O; werase = ^W; lnext = ^V
另外,我尝试了3个串口,线我也重新插了几次,还是不行。
