Windows NT allows printer connections using ports LPT1 through LPT9when using the NET USE command from the command prompt.
In Windows NT Help it states that the devicename parameter used withthe NET USE command allows devicenames LPT1: through LPT3:. This isnot totally correct. It is possible to use devicenames LPT4: throughLPT9: as well.
Under Windows NT Help/Command Reference/Net Use, the Devicenameparameter states the following:
Assigns a name to connect to the resource or specifies the device to be disconnected. There are two kinds of devicenames: disk drives (D: through Z:) and printers (LPT1: through LPT3).
This implies that printer devicenames can only be LPT1: through LPT3:,however, devicenames can actually be through LPT9:.
NOTE: Some MS-DOS applications may not be able to access printerdevicenames greater than LPT3:.
