 *
 * Repeater / Remote Functions:
 * "Simple" Mode:  * - autopatch access, # - autopatch hangup
 * Normal mode:
 * See the function list in rpt.conf (autopatchup, autopatchdn)
 * autopatchup can optionally take comma delimited setting=value pairs:
 *  
 *
 * context=string		:	Override default context with "string"
 * dialtime=ms			:	Specify the max number of milliseconds between phone number digits (1000 milliseconds = 1 second)
 * farenddisconnect=1		:	Automatically disconnect when called party hangs up
 * noct=1			:	Don't send repeater courtesy tone during autopatch calls
 * quiet=1			:	Don't send dial tone, or connect messages. Do not send patch down message when called party hangs up
 *
 *
 * Example: 123=autopatchup,dialtime=20000,noct=1,farenddisconnect=1
 *
 *  To send an asterisk (*) while dialing or talking on phone,
 *  use the autopatch acess code.
 *
 *
 * status cmds:
 *
 *  1 - Force ID
 *  2 - Give Time of Day
 *  3 - Give software Version
 *
 * cop (control operator) cmds:
 *
 *  1 - System warm boot
 *  2 - System enable
 *  3 - System disable
 *  4 - Test Tone On
 *  5 - Dump System Variables on Console (debug)
 *  6 - PTT (phone mode only)
 *
 * ilink cmds:
 *
 *  1 - Disconnect specified link
 *  2 - Connect specified link -- monitor only
 *  3 - Connect specified link -- tranceive
 *  4 - Enter command mode on specified link
 *  5 - System status
 *  6 - Disconnect all links
 *
 * remote cmds:
 *
 *  1 - Recall Memory MM  (*000-*099) (Gets memory from rpt.conf)
 *  2 - Set VFO MMMMM*KKK*O   (Mhz digits, Khz digits, Offset)
 *  3 - Set Rx PL Tone HHH*D*
 *  4 - Set Tx PL Tone HHH*D* (Not currently implemented with DHE RBI-1)
 *  5 - Link Status (long)
 *  6 - Set operating mode M (FM, USB, LSB, AM, etc)
 *  100 - RX PL off (Default)
 *  101 - RX PL On
 *  102 - TX PL Off (Default)
 *  103 - TX PL On
 *  104 - Low Power
 *  105 - Med Power
 *  106 - Hi Power
 *  107 - Bump Down 20 Hz
 *  108 - Bump Down 100 Hz
 *  109 - Bump Down 500 Hz
 *  110 - Bump Up 20 Hz
 *  111 - Bump Up 100 Hz
 *  112 - Bump Up 500 Hz
 *  113 - Scan Down Slow
 *  114 - Scan Down Medium
 *  115 - Scan Down Fast
 *  116 - Scan Up Slow
 *  117 - Scan Up Medium
 *  118 - Scan Up Fast
 *  119 - Transmit allowing auto-tune
 *  140 - Link Status (brief)
 *
 *
 *
 * 'duplex' modes:  (defaults to duplex=2)
 *
 * 0 - Only remote links key Tx and no main repeat audio.
 * 1 - Everything other then main Rx keys Tx, no main repeat audio.
 * 2 - Normal mode
 * 3 - Normal except no main repeat audio.
 * 4 - Normal except no main repeat audio during autopatch only
