I am exploring the possibility of converting to Linux, but I am having a bit of difficulty with a very important function. Specifically, I have a variety of test and measurement equipment that communicates over RS-232 with the computer. In Windows, I have a functional connection- I can read and write to the equipment utilizing HyperTerminal, RealTerm, and I have even written a Visual Basic macro to read the equipment directly into an Excel spread sheet. I have the Linux distro (Ubuntu 7.10) loaded in a double boot configuration with Windows XP. My communications setup works hardware-wise in XP on this particular box, but I can not seem to get Linux to work with the serial ports, and have spent a good deal of time looking for a solution. I have tried QtDMM (which is the ideal solution, but not set up for the meters I am working with), minicom, which is looking for a file "termcap.h" which does not appear to be on the system, and cutecom, which is giving me trouble with loading (both minicom and cutecom are attempts at duplicating HyperTerminal, if I understand the literature correctly, and RealTerm, my favorite, is not ported to Linux). Äpparently, most Linux developers think the only reason one uses a computer is to talk to the Internet, and most of the serial communications documentation seems to focus on modem applications.
Has anyone out there had any experience with this? Can someone point me in the right direction to figure out how to accomplish this? I really don't want to spend the rest of my life tied to Windows because of this issue...
