Line Field

This field contains the device name of the line (port) associated with the Devices entry. For instance, if the modem associated with a particular entry were attached to the /dev/cua/a device (serial port A), the name entered in this field would be cua/a. There is an optional modem control flag, M, that can be used in the Line field to indicate that the device should be opened without waiting for a carrier. For example:

cua/a,M
