3.3.6 Making Connection to a Resource

For the final step, the server returns a TID to the client, indicating that the user has been authorized access and that the resource is ready to be used. It also sets the ServiceType field to "A" to indicate that this is a file service. Available service types are:

• "A" for a disk or file

• "LPT1" for a spooled output

• "COMM" for a direct-connect printer or modem

• "IPC" for a named pipe

The output is:

Now that a TID has been assigned, the client may issue any sort of command that it would use on a local disk drive. It can open files, read and write to them, delete them, create new files, search for filenames, and so on.
