Problems with minicom on CentOS 4.4
...hat CentOS is a community based binary distro of RHEL. Before that I used to use RH9(it is quite out of date for my newly upgraded PC) as my host environment to work on embedded systems. The installation procedure went smoothly and after that everything looked functional, however, I found that the minicom had a problem - When I started it in GNOME terminal window using ?minicom -s? for the time, the program halted like this: [root at localhost ~]# minicom -s minicom: WARNING: configuration file not found, using defaults And then I could not input any commands, I had to close the GNOME terminal wi...

Minicom 1.75 Vulnerability
hi ppl, well, here is another standard buffer overrun vulnerability, which may sometimes lead to root compromise (not always. not in new distributions, fortunately). Current Slackware and current RedHat don''t install minicom suid root, only sgid/uucp, which is not *that* dangerous. But when you build minicom from source, it asks you to do "chmod +s" on it. Summary: Vulnerability in minicom allows (certain) local users to obtain group "uucp" privileges and, in certain cases, root privileges....

Minicom and Ncurses
Hi, I have to do some maintenance on a CentOS 7 proxy installed on a routerboard without a video card. The only way to access this machine directly is via Minicom and serial port. I'm using NetworkManager TUI (nmtui) to configure network interfaces, but Ncurses rendering in Minicom works in the sense that chickens fly and horses swim. What you get is a forest of question marks with a few barely recognizable options lost in between. Is there some magica...

minicom
I need a terminal program, such as minicom, which I see is not part of my Strongbolt install of CentOS+BQ loaded on a RaQ 4 system. Does anyone know if a standard rpm for minicom should work or where to get a package that will provide minicom or other terminal program? Or, perhaps there is another terminal program installed in my system...

Terminal emulation and serial ports
I have to reinit a firewall that can only be done from its console port, and I do not have an XP system with Hyperterminal on it. So I went through the archive and learned that minicom could do the job for me. I installed it and went to configure it (minicom -s). I can set the speeds, but the challenge is selecting the serial device. I have a Serial-to-USB dongle, and when I connect it, the gnome hardware browser is showing a FIDI usb serial converter that was not there be...

/dev/ttyS1 on Xen (domain 0)
Hi, On a regular FC4 machine there are 76 device file for /dev/ttyS*. I tried running minicom on a Xen machine (domain 0) whose serial port is connected to a different machine (a machine with no VGA/Keyboard/Mouse). It gave the following error: minicom: WARNING: configuration file not found, using defaults Device /dev/ttyS1 access failed: No such file or directory. So I checked, and ls...

is it possible to login to a switch via RS232 / serial port from the shell?
Hi all I have a problem switch in our data centre, which is connected to a linux server via a serial cable. I know I can / could access the switch from my Windows PC back at the office, using hyperterm, but trying to access it using minicom just doesn't seem to work. I have changed the comms in minincom to use /dev/tty0 & the baud rate to 9600, yet I can't seem to connect with minicom. Does anyone know how to connect to a serial device from the console? -- Kind Regards Rudi Ahlers CEO, SoftDux Office: 087 805-9573 Fa...

Minicom capture file
I'm trying to capture text data coming in on serial port to put into a plot on a web page. Running minicom 2.3 on a Fedora 9 box the capture file is updated immediately. Running minicom 2.1, stock on a Centos 5.x box the capture file doesn't update until you exit capture mode. Is there any way to have it update immediately or is there an alternative application to write incoming data to a text file....

telnet to serial connection?
...folks! here's my situation: i've got two WTI RPB+ remote power switches (essentially a 5-port power strip which you can control via serial interface to make each of the ports switch on and off independently). they work fine; i plug a DB-9 cable into the back of my machine, fire up minicom, and i have full control. however, my eventual plan is to use these as fencing devices for a small RHCS cluster i'm building, and so the fencing process will need to be scriptable. RHCS wants to fence by invoking a "/sbin/ fence_<whatever>" script that uses Net::Telnet to...

TCP port to TTY/Serial Port?
...ure my system such that I have a TCP port listening which will send all data it receives to a serial port. ie:?? tcp/2112? -->? /dev/ttyS0 My goal would be to be able to: Use netcat to create the listen and redirect to a serial port: ? $ nc -l 2112 > /dev/ttyS0 Then in another window, run minicom at /dev/ttyS0 Then in a 3rd window, ? $ telnet localhost 2112 ?"Type things, hello world" But, I can never get the text to show up in the minicom window. I read different variations on the netcat command, including: $ nc -l 2112 <> /dev/ttyS0 or $ nc -l 2112 > /dev/ttyS0 &lt...

Serial communication problem
...connecting them using a pair of virtual serial ports. The virtual serial ports are created using the native Linux app VSPDL from www.tibbo.com. I have made links for the com ports in c:\dosdevices to the appropriate files in /dev. The virtual port pair appears to work ok when I test it using two minicom sessions. I can also read the AIS data from AISMon using Minicom. However, SeaClear doesn't receive any of this data. If I start SC from the terminal I get the following message when AISMon sends a dataset into the virtual COM port pair: fixme:comm:set_queue_size insize 4096 outsize 8192 unim...

Debugging the hypervisor
...ort, but nothing seems to work. Using mercurial, I got xen-3.2-testing.hg. I followed the steps in crashdb.txt in the docs/misc/ folder: set debug=y in Config.mk, crash_debug=y in xen/Rules.mk I also added -fno-omit-frame-pointer to these file as well. I compiled with no errors and booted with minicom connected to the workstation via com1 but when I do Ctrl-A three times to connect, nothing happens. The debuggee boots find and gives me the login screen as normal. Is there a special time to hit the Ctrl-A in minicom? Should the kernel wait for a connection from gdb? I''ve tried various...

Serial console with pxelinux on Soekris net4501
...;m PXE booting using pxelinux. Everything seems to be working splendidly, except for the fact that I can't seem to make pxelinux understand use the net4501's serial console port correctly. The net4501 uses the serial console as its primary interface; I'm using a null modem cable and minicom to operate with it. At boot, its startup messages go out over the serial console and everything works as it should, until the point where it gets to finding pxelinux.0 from my tftp server. As soon as the bios finds and loads it, I get garbage over minicom that looks like this: 3;01H3;97HP3;01HX...

External Dial-up Modem
I am having an issue with Centos 6 and an external USRobotics modem. We use the modem as part of a last resort SMS paging system. Across multiple Dell servers, different models, I can't not get the modem to respond to simple AT commands while using Minicom. At the same time if I connect the server to a console port on a switch I can successfully access the switches serial console. So I know the serial port itself is working. The modem still works fine if connected to a Centos 5 server. Any thoughts? Graham Johnston Network Planner Westman...
