Hi John and all: This is US-Robotics 56k external fax/modem connected to ttyS1. There is no problem to run wvdial but I can't get any respons from minicom, even pressing typical combinations of keystroke gives me no respons, for instance, ctrl+z dos nothing, i can't close the program and need to kill minicom from another console. Besides, modem accepts dial-ins but it is another issue.
