= DESCRIPTION: = Opens a new port connection.

OPEN is a native value. = ARGUMENTS: =
 * spec -- (Type: file url port object block)

= REFINEMENTS: =

 * /string -- Translates all line terminators.
 * /direct -- Opens the port without buffering.
 * /seek -- Opens port in seek mode without buffering.
 * /new -- Creates a file. (Need not already exist.)
 * /read -- Read only. Disables write operations.
 * /write -- Write only. Disables read operations.
 * /no-wait -- Returns immediately without waiting if no data.
 * /lines -- Handles data as lines.
 * /with -- Specifies alternate line termination.
 * end-of-line -- (Type: char string)
 * /allow -- Specifies the protection attributes when created.
 * access -- (Type: block)
 * /mode -- Block of above refinements.
 * args -- (Type: block)
