Block mode addressing must be used in order to specify an "id" parameter in the
QCOM.SYS configuration line.
3.8.2 Discrete Addressing
In this mode, each serial port on the adapter is addressed discretely from the other ports.
The interrupt status register is not used. Each port is installed as a SERIALx port as defined by
the IBM Micro Channel architecture. IBM Micro Channel computers typically support serial
ports addressed in this fashion as "SERIAL1" through "SERIAL8".
If discrete mode addressing is used, each port must be individually specified in the
QCOM.SYS configuration line as shown for "other serial ports" (see page 9).
