The appropriate import command to use would depend partly on what type of
data (polygon, line, or site).  You don't specify what the output command
was used to export this data from arc/info but that command would then
determine the appropriate grass command to use.  I don't think this is a
data format that the v.in.arc command was intended to use (either polygon
or line).

Try asking your data source what they used to create this file and if it
is something importable by grass.  Typicall arc/info data export commands
would be "export" for other arc/info systems, "ungenerate" for v.in.arc 
in grass, "arcdlg" for dlg format data, or "arcdxf" for cad format data.
It would be a good idea to request data export files in a format you know
you can read into grass such as dlg or "ungenerate" format for v.in.arc.
So...  Check back with your source and figure it from there.
