The Linux Serial HOWTO: Introduction 1. IntroductionThis is the Linux Serial HOWTO. This covers info on the Serial Port that is not available in other HOWTO's. It includes how to set up modems under Linux, some serial tips, and troubleshooting advice. Another HOWTO exists for terminals (see Related HOWTO's). This HOWTO addresses Linux running on Intel x86 hardware, although it might work for other architectures.1.1 CopyrightCopyright (c) 1993 - 1997 by Greg Hankins, 1998 by David Lawyer.

You may do the equivalent of "stty ...", open ports in various modes, and more.Text-Terminal-HOWTO is all about character-cell terminals (dumb terminals ?).1.3 Release NotesI, David Lawyer, am the new maintainer (Greg Hankins was the original author and maintainer). This is a minor revision and I haven't checked out much of the info to see if it's up-to-date. There is much work to do on this. Let me know what's wrong or missing. In the future, I may do a 3-way split on this Howto: 1. Info on terminals into Text-Terminal-HOWTO. 2. Info on modems into a new Howto: Modem-HOWTO. 3. More info on the Serial Port added to this Howto. Thus look for major new versions in Aug. or Sept. 1998.1.4 New Versions Of This DocumentNew versions of the Serial HOWTO will be available atftp://sunsite.unc.edu:/pub/Linux/docs/HOWTO/Serial-HOWTO and mirror sites. There are other formats, such as Postscript and DVI versions in the other-formats directory. The Serial HOWTO is also available at http://sunsite.unc.edu/LDP/HOWTO/Serial-HOWTO.html and will be posted to comp.os.linux.answers monthly.1.5 FeedbackPlease send me any questions, comments, suggestions, or additional material.
