编译ckermit源码

先解压源码
tar zxvf cku302.tar.gz
编译
make linux
如果出现以下错误

ckufio.o：在函数‘zvpass’中：
ckufio.c:(.text+0xbb81)：对‘crypt’未定义的引用
ckcnet.o：在函数‘locate_srv_dns’中：
ckcnet.c:(.text+0x40b5)：对‘__res_search’未定义的引用

collect2: error: ld returned 1 exit status
makefile:1202: recipe for target 'xermit' failed

make[1]: *** [linuxa] Error 2
make[1]: Leaving directory '/opt/kermit'
makefile:5473: recipe for target 'linux' failed
make: *** [linux] Error 2

解决方法是用vim 打开 makefile找到规则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"

在最后一行 “-lm “后边加上 空格 -lcrypt -lresolv
如图

再编译一次
make linux
编译完成。
生成的wermit就是了，一般情况下把它拷贝到/usr/local/bin下并重命名为kermit。

配置ckermit

在自己的家目录下创建文件 .kermit
vim ~/.kermrc
加入以下内容

set line /dev/ttyUSB0 //根据实际情况改成自己的串口设备
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

启动kermit

直接在命令行中输入kermit回车
如果输出以下信息

/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,
  Trustees of Columbia University in the City of New York.
Type ? or HELP for help.
(/opt/kermit/) C-Kermit>q

需要将设备文件的权限修改一下(每次插入设备都要重新修改权限)
sudo chmod 777 /dev/ttyUSB0

再次启动输出

C-Kermit 8.0.211, 10 Apr 2004, for Linux
 Copyright (C) 1985, 2004,
  Trustees of Columbia University in the City of New York.
Type ? or HELP for help.
(/opt/kermit/) C-Kermit>

就可以用了，再C-Kermit>输入c就连接上了串口

u@u-pc:/opt/kermit$ kermit
C-Kermit 8.0.211, 10 Apr 2004, for Linux
 Copyright (C) 1985, 2004,
  Trustees of Columbia University in the City of New York.
Type ? or HELP for help.
(/opt/kermit/) C-Kermit>c
Connecting to /dev/ttyUSB0, speed 115200
 Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.
----------------------------------------------------
OK
后边就是一大堆的开发板输出的信息

要断开串口连接 同时按下键盘ctrl+\键，松开后再按下c键。

关于kermit的更多用法后续更新。
