tar zxvf cku302.tar.gz
編譯
make linux

解決方法是用vim 開啟 makefile找到規則linuxa

linuxa:
        @echo 'Making C-Kermit $(CKVER) for Linux 1.2 or later...'
        @echo 'IMPORTANT: Read the comments in the linux section of the'
        @echo 'makefile if you have trouble.'
        $(MAKE) xermit KTARGET=$${KTARGET:-$(@)} "CC = gcc" "CC2 = gcc" \
        "CFLAGS = -O -DLINUX -pipe -funsigned-char -DFNFLOAT -DCK_POSIX_SIG \
        -DCK_NEWTERM -DTCPSOCKET -DLINUXFSSTND -DNOCOTFMC -DPOSIX \
        -DUSE_STRERROR $(KFLAGS)" "LNKFLAGS = $(LNKFLAGS)" "LIBS = $(LIBS) -lm"

在最後一行 “-lm “後邊加上 空格 -lcrypt -lresolv
如圖

再編譯一次
make linux
編譯完成。
生成的wermit就是了，一般情況下把它拷貝到/usr/local/bin下並重命名為kermit。

配置ckermit

在自己的家目錄下建立檔案 .kermit
vim ~/.kermrc
加入以下內容

set line /dev/ttyUSB0 //根據實際情況改成自己的串列埠裝置
set speed 115200
set carrier-watch off
set handshake none
set flow-control none
robust
set file type bin
set file name lit
set rec pack 1000
set send pack 1000
set window 5

啟動kermit

直接在命令列中輸入kermit回車
如果輸出以下資訊

/dev/ttyUSB0: Permission denied
?SET SPEED has no effect without prior SET LINE
C-Kermit 8.0.211, 10 Apr 2004, for Linux
 Copyright (C) 1985, 2004,

Type ? or HELP for help.
(/opt/kermit/) C-Kermit>q

需要將裝置檔案的許可權修改一下(每次插入裝置都要重新修改許可權)
sudo chmod 777 /dev/ttyUSB0

再次啟動輸出

C-Kermit 8.0.211, 10 Apr 2004, for Linux

就可以用了，再C-Kermit>輸入c就連線上了串列埠

[email protected]:/opt/kermit$ kermit

----------------------------------------------------
OK
後邊就是一大堆的開發板輸出的資訊

要斷開串列埠連線 同時按下鍵盤ctrl+\鍵，鬆開後再按下c鍵。
