編譯ckermit源碼
先解壓源碼
tar zxvf cku302.tar.gz
編譯
make linux
如果出現以下錯誤

解決方法是用vim 打開 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下並重命名爲kermit。
配置ckermit
在自己的家目錄下創建文件 .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口設備
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
啓動kermit
直接在命令行中輸入kermit回車
如果輸出以下信息
/dev/ttyUSB0: Permission denied
?SET SPEED has no effect without prior SET LINE

Type ? or HELP for help.
(/opt/kermit/) C-Kermit>q
需要將設備文件的權限修改一下(每次插入設備都要重新修改權限)
sudo chmod 777 /dev/ttyUSB0
再次啓動輸出

就可以用了,再C-Kermit>輸入c就連接上了串口
u@u-pc:/opt/kermit$ kermit

----------------------------------------------------
OK
後邊就是一大堆的開發板輸出的信息
要斷開串口連接 同時按下鍵盤ctrl+\鍵,鬆開後再按下c鍵。
