Exit Minicom Serial Port Setup
After these steps it should work fine, but my minicom is showing 'offline'. Press Enter to exit to main menu then Esc to start minicom. Open serial port setup and write serial device as /dev/ttyUSB0 and write Hardware Flow Control to NO. Open the minicom by using command sudo minicom -o -s -w.
I am sure you know that already, but just to be sure we are doing the same and to quickly figure out your problem. 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.Replied by opal on topic who to exit minicom connected to Raspi. The AT command set lets you communicate directly to the modem for troubleshooting. Welcome to.The protocol that a computer uses to communicate with standard Hayes-compatible modems is referred to as the AT command set. Start Minicom as a terminal program sudo minicom.
Using minicom, you can display and change settings on the modem by issuing commands. You can also dial out directly, test communications, and change settings.The procedure in the following section illustrates a session where we use minicom to communicate directly to the modem. So I suspect my syntax is wrong.With minicom, you can send AT commands directly to your modem to get information about its features and current state. My problem is that for some reason when I do this it doesn't give me the results of the prior commands sent like showifs. This is what I've tried: /bin/sh. The problem occurs when i run this from jenkins.Exiting from Minicom on a shell script.
The first 11 S registers are standard among most modems.At 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. Each AT command starts with a letter, except for some that can be preceded by an ampersand (&) or a pound sign (#).S registers-Each "S" register contains a piece of information that can be stored and used on the modem.
(You may need to restart minicom for the new settings to take effect. This saves configuration settings to the /etc/minirc.dfl file.Exit-Highlight Exit and Press Enter. A message will say Configuration Saved. Then press Enter to return.) Press Enter to return to the menu.Save settings-Highlight Save setup as dfl and press Enter. (Press E, and then press I to select 115200 BPS as the speed at which your computer communicates to the modem. Examples of device names include:/dev/ttyS0-For the first serial port (also called COM1)./dev/ttyS1-For the second serial port (also called COM2)/dev/ttyACM0-For the first serial interface to a USB modem.After typing the device name, press Enter.Change line speed-Change the Bps/Par/Bits lines to read 115200 8N1, if it doesn't already say that.
Here are characters you can add after the DT (for tone dialing) or DP (for pulse dialing):W-Wait for a dial tone. The letters and numbers that follow the AT change or display the selected values.Show profiles-To show the settings on the modem, type the following:If you get a dial tone, or are not able to dial out and connect to the remote modem, you may find that you need to pause or wait for secondary tones during the dial-up procedure. In this example, several items were set during initialization:The number of seconds to wait for a carrier is set to 45 (S7 = 45)Receive line signal detect is set to follow the carrier's state (&c1)At this point, try some AT commands to get to know your modem better. If you don't see OK, you are not communicating to the modem. Then type minicom to restart it.)OPTIONS: History Buffer, F-key Macros, Search History Buffer, I18nThis shows that minicom started successfully, and when it sent an AT command to initialize the modem, the modem received it and responded with OK.

The next section describes how to add the settings you come up with for your modem so that they are made permanent and used each time your modem connection starts up.
