Module Name:
Argument
Abstract:
Argument processing for the Mode utility. After parsing the
arguments off the command line, a minimum verification is done and
a request packet is formed and returned.
The request packet is eventually routed to the handler for a specific
device, which performs further verification and takes proper
action.

Notes:
BUGBUG ramonsa 7/9/91
The number of stop bits can be 1, 1.5 or 2, Currently the library will
not support floating point operations, so there are no
floating-point-number arguments. We use a flag argument to handle
the 1.5 case. This should be fixed whenever the library supports
floating point.
The mode command-line can take any of the following forms:
MODE [/?]
MODE [device] [/STATUS]
MODE device CP PREPARE=string
MODE device CP REFRESH
MODE device CP SELECT=codepage
MODE device CP [/STATUS]
MODE LPTn[:] [COLS=c] [LINES=l] [RETRY=r]
MODE LPTn[:] = COMm[:]
MODE COMm[:] [BAUD=b] [PARITY=p] [DATA=d] [STOP=s] [RETRY=r]
MODE CON[:] [COLS=c] [LINES=l]
MODE CON[:] [RATE=r DELAY=d]
