About make and model of modem
Hi folks,
I have an old external serial modem without indication of make and model. Please advise what command and/or procedure to find them. TIA B.R. satimis |
Greetingz!
If you don't even have an FCC ID sticker on the modem, then (if it's PCI, and not ISA) I would advise throwing it into a system and booting a Live Linux CD (like Knoppix). Once booted, just run something like "lspci" or "lshw" to find out the details. If anything, one of those commands should give you enough information that a quick google search should pull up the rest! However, don't be discouraged if it doesn't, just head over to LinModems. Have a good one! |

Thanks for your advice. It is a serial modem connected to COM port. dmesg printout a large file. What shall I "grep"? TIA B.R. satimis |
It's a serial modem hooked into a COM port? With no stickers or labels?
Honestly, I'd do one of three things at this point; A: Safe Idea Take a few photos of it, stuff them in your blog, then do a TinEye.com search on the images and see what comes up. (Be sure to crop-down the photos to just the modem on a white background!) B: Kinda Lame Idea Post the picture in this thread as an attachment, then over on craiglist.com and find out if anyone knows what it is. C: Fun Idea Take a screwdriver to it and see if there's (a) model/serial/part number(s) on the inside. Then google those up! |

If you don't have stickers/numbers/etc., of ANY type on that modem (which I doubt...SOMETHING of an identifier will be there), you can try to run minicom, and query the modem directly. If you have the modem plugged into the first serial port, that should be /dev/ttyS0, so set up minicom accordingly, and issue "atixx", where the "xx" is a number, between 1 and 9. You MIGHT be able to go higher, but those are the interrogation codes in the Hayes command set, the I being there specifically for Plug-n-Play identification. If you go higher than 9, and that register isn't there, the worst that will happen is you'll get ERROR returned, so give it a try. Check the entire Hayes command set here: http://en.wikipedia.org/wiki/Hayes_command_set |
HI TB0ne,
Thanks for your advice. The only indication on the case is "56K Top Modam" made in Taiwan. This is a virtual machine running Oracle VBox (VirtualBox) as virtualizer. The host is running Ubuntu 10.04 64-bit. The VM (guest) is running WinXP. The old serial modem can run on the host without problem. But it can't be installed on VM needing the driver. A big ? is on the modem in Device Manager. 1) On host without forwarding the modem to the VM running; # wvdialconf /etc/wvdial.conf Code:
Editing `/etc/wvdial.conf'. 2) Forwarding the port to the VM # wvdialconf /etc/wvdial.conf Code:
Editing `/etc/wvdial.conf'. http://open.nit.ca/wiki/?WvDial http://open.nit.can Server NOT found. B.R. satimis |

(The 56k ones can be set to 56k phone line data rate, where slower ones can't be set to go that fast, but apart from that kind of fine detail, they are identical, identical identical. If wvdial (or kinternet, or whatever) can deal with one, it can deal with all the normal consumer modems. Oh, and don't confuse the speed on the phone line with speed on the serial interface between the PC and the modem - in this case, 115k; there is probably a slight speed advantage in setting the RS-232 link up to the slightly faster speed, such as this 115k (with 56k phone line speed), but the speed overall is always going to be rather slow by modern standards.) You plug them in and they do what they do (which isn't much). You can still have problems, as has been described, at the VM level or at the level of setting the modem up for correct dialling or authentication with the ISP, but its not a driver problem, or anything else that can be cured with a make or model number. Which is perhaps as well because Quote:
