Recently I came out of the 1990’s, and moved to an IBM laptop that does not have a serial port<\/em>… Gasp!<\/p>\n

Of course, this is not a big deal to alot of people, but I’m a server guy.\u00a0 I do terminal sessions to Sun\/Solaris servers and Cisco routers and such;\u00a0 I really can’t live without a serial port.\u00a0 So I basically had 2 options:<\/p>\n

    \n
  1. Go back to my old latop (nope, no way, nahgahdah)<\/li>\n
  2. Get a USB attached serial port<\/li>\n<\/ol>\n

    …so after reading a ton of reviews at NewEgg.com, I finally settled on the CABLES UNLIMITED USB-2920 USB 2.0 to Serial DB9 Adapter<\/a>.\u00a0 At the time I bought it, it was on sale and had a shipping special.\u00a0 But at the time of this writing it is $16.99.\u00a0 …Still not bad, really.<\/p>\n

    First, Windows<\/h3>\n

    As it happens, when I first bought it, I connected it to my laptop, and I fired up a Windows XP guest in VMWare Server 2 on my Opensuse 11.2, and “virtually” connected the USB to the XP guest (can’t do *that* in ESX… nyah, nyah).\u00a0 The driver installation in Windows was a little weird,\u00a0 since the driver installation was a little language-challenged…\u00a0 But if you know what you’re doing, you can get it done.\u00a0 Once it was all set up in Windows, it was easy to use in Hyper Terminal and Putty, and it really worked perfectly.<\/p>\n

    Then, Linux<\/h3>\n

    A few days later, I needed to do a serial connection again.\u00a0 This time I didn’t feel like firing up my VM guest, so decided to stop playing around, and configure it natively in Linux for use in minicom.\u00a0 Here’s where it gets good…\u00a0 It is sooooo easy to setup in Opensuse, and I hope\/assume it is nearly as easy in other distros, though I’ve not tested it.\u00a0 Here’s basically what I did:<\/p>\n

    Step 1:\u00a0 Plug into adapter into USB port<\/p>\n

    Step 2:\u00a0 Launch minicom -s<\/code> (to enter configuration)<\/p>\n

    Step 3:\u00a0 Configure the port as \/dev\/ttyUSB0\u00a0 (that’s a zero, though it could be a 1 on yours if you have multiple), and save as “dfl” (default)<\/p>\n

    Step 4:\u00a0 Enjoy!<\/p>\n

    I hope this helps…<\/p>\n
