#Minicom alternative serial#

If you don't see OK, you are not communicating to the modem. This shows that minicom started successfully, and when it sent an AT command to initialize the modem, the modem received it and responded with OK. OPTIONS: History Buffer, F-key Macros, Search History Buffer, I18n Press Ctrl+A, and then X to quit minicom. (You may need to restart minicom for the new settings to take effect. This saves configuration settings to the /etc/minirc.dfl file.Д®xit-Highlight Exit and Press Enter. Save settings-Highlight Save setup as dfl and press Enter. Then press Enter to return.) Press Enter to return to the menu. (Press E, and then press I to select 115200 BPS as the speed at which your computer communicates to the modem.

dev/ttyACM0-For the first serial interface to a USB modem.ДЄfter typing the device name, press Enter.Д¬hange line speed-Change the Bps/Par/Bits lines to read 115200 8N1, if it doesn't already say that. dev/ttyS1-For the second serial port (also called COM2) dev/ttyS0-For the first serial port (also called COM1). Set serial device-If the serial device listed does not represent the one connected to your modem, press A and type the name of your serial device. Refer to Table 13-1 for other minicom functions you can use. The first 11 S registers are standard among most modems.ДЄt this point, I assume that you have installed and configured a modem as described in the Choosing a Modem section earlier in this chapter and that you know the serial device (such as /dev/ttyS0) used to communicate with that modem. Some modems can contain over 300 S registers, which can be incompatible with S registers on other modems. S registers-Each 'S' register contains a piece of information that can be stored and used on the modem. Each AT command starts with a letter, except for some that can be preceded by an ampersand (&) or a pound sign (#). For the most part, we are interested in working with:ДЄT commands-These include a standard set of commands used to operate most modems today. Using minicom, you can display and change settings on the modem by issuing commands. The procedure in the following section illustrates a session where we use minicom to communicate directly to the modem.

You can also dial out directly, test communications, and change settings. With minicom, you can send AT commands directly to your modem to get information about its features and current state. Minicom is a Linux-equivalent to the HyperTerminal utility that you may be familiar with in Microsoft operating systems. The minicom command provides an interface for communicating with devices that are connected to serial ports. If you were not able to get a dial-out connection going as described earlier with the wvdial command or Network Configuration window, you can try using minicom. The AT command set lets you communicate directly to the modem for troubleshooting. The protocol that a computer uses to communicate with standard Hayes-compatible modems is referred to as the AT command set.
