Ed, Many thanks for the reply -- I am using an IOGEAR GUC232A, which works fine on my SuSe 9.3 dev machine.
Just to make sure I flashed to the latest image 2005.51-13 -- thus replacing my custom kernel. No /dev/ttyUSB0, etc. I don't need a getty, just a serial device. We hope to be able to talk to the rs-232 port on a very specialized bit of test equipment using software that already runs on a SuSe 9.3 laptop. Our app builds fine under the SDK_ARM, and is very generic -- only using bits of: #include <termios.h> #include <stdio.h> #include <unistd.h> #include <fcntl.h> #include <sys/signal.h> #include <sys/types.h> Once I am able to talk to the device our hope is to add a GUI for display of acquired spectra, calibration, etc. It would be wonderful not to have to lug a laptop about as is done now. As of now -- I am thinking it may be the hub -- still looking.
