 |``Send APRS Packet``|Sends a raw APRS packet to APRS-IS in case an open connection to the APRS-IS network has been established|``packet`` (string)|
 |``Receive APRS Packet``|Receives an APRS packet to APRS-IS in case an open connection to the APRS-IS network has been established. The default setting uses the parameter values ``immortal`` = ``True`` and ``raw``= ``False``, meaning that aprslib will try to re-establish the connection in case it is lost and will also auto-decode APRS packets when received|``immortal`` and ``raw`` (both boolean params)|
 |``Get <field name> Value from APRS Packet``|various wrappers; e.g. ``Get Message Text Value From APRS Packet`` will return the decoded message string if it is present in the message|``aprs_packet``. If you specify a field that does not exit in the packet, this keyword will cause an error. Both raw and decoded messages are supported.|
-|``Get Value From APRS Packet``|called by the aporementioned ``Get <field name> Value fron APRS Packet`` functions |``aprs_packet`` and ``field_name``. If you specify a field that does not exit in the packet, this keyword will cause an error. Both raw and decoded messages are supported.|

 |``Get APRS MsgNo``, ``Set APRS MsgNo``, ``Increment APRS MsgNo`` and ``Get APRS MsgNo as Alphanumeric``| Gets and sets the MsgNo that you can use for building up your own messages (aka library-maintained counter value). The ``alphanumeric`` keyword provides the message number in a format which [supports the more recent replyack scheme](http://www.aprs.org/aprs11/replyacks.txt). An ``increment`` to the value of ``675`` (``ZZ``) will automatically reset the value to ``0`` (``AA``). Both ``Get APRS MsgNo`` methods do NOT automatically increment the message number.|``Set APRS MsgNo`` allows you to set a numeric value between 0 and 675 (equals ``AA`` to ``ZZ``). All other keywords have no parameters.|
