modem - usb to serial configuration
I have a serial modem connected to a usb port using an adapter cable. The system is a HP DL360. RedHat ES3.0
I am using the device /dev/ttyUSB0
When I issue the command "mgetty ttyUSB0" I get the following output in the log file.
How do I get the system to see the modem.
