Description: modem编程
本地机使用ATDT命令拨号，远程机设为自动响应方式，即可进入联机方式， 进行终端通信。 在联机方式下，按PageUp键上载文件，按PageDn键下载文件，Ctrl-O呼出主菜单，退出联机方式使用Ctrl-D键。退出终端仿真器使用EXIT命令。
主程序使用C语言编写。使用早期的C编译器可以进行编译。终端方式为VT100.-modem programming local machine using the ATDT command dial, the remote machine is set to automatically respond to the way, you can enter the line for terminal communication. In-line mode, press PageUp key to upload files, download the file by PageDn keys, Ctrl-O exhaled main menu, quit-line use Ctrl-D keys. Withdraw from the terminal emulator using the EXIT command. The main program using the C language. The use of the early C compiler can be compiled. Terminal for VT100. Platform: |
