 + ifpic - AuScope IF PIC Control command
 +
 +Syntax: ​   ifpic=switch,​diode,​SLatt,​SRatt,​XLatt,​XRatt,​p5db
 +
 +Response: ​ ifpic/​0,​switch,,​SLatt,​SRatt,​XLatt,​XRatt,​
 +           ​ifpic/​1,​volts3p3,​volts5,​volts12,​spare
 +           ​ifpic/​2,​boxTempC,​boxRH,​MaserTempC,​MaserRH,​MaserBatt,​GenBatt
 +
 +
 +Settable parameters:
 +switch ​    IF monitor switch selecition, one of "​SL",​ "​SR",​ "​XL",​ or "​XR"​
 +           (for SLCP, SRCP, XLCP, or XRCP respectively). Default is no
 +           ​change.
 +diode      Noise diode control, one of "​on"​ or "​off"​. Default is no change
 +           Not available in monitor response..
 +SLatt      SLCP attenuation,​ value are 0 to 15.5 dB in 0.5 dB steps. Default
 +           is no change.
 +SRatt      SRCP attenuation,​ value are 0 to 15.5 dB in 0.5 dB steps. Default
 +           is no change.
 +XLatt      XLCP attenuation,​ value are 0 to 15.5 dB in 0.5 dB steps. Default
 +           is no change.
 +XRatt      XRCP attenuation,​ value are 0 to 15.5 dB in 0.5 dB steps. Default
 +           is no change.
 +p5dB       0.5 dB attenuator state toggle, only allowed value is "​toggle"​.
 +           ​Default is no change. Not available in monitor response.
 +
 +Monitor-only parameters:
 +volts3p3 ​  3.3 volt power supply voltage, volts..
 +volts5 ​    5 volt power supply voltage, volts
 +volts12 ​   12 volt power supply voltage, volts.
 +spare      TBD.
 +
 +boxTempC ​  Box temperaure, degrees C.
 +boxRH      Box relative humidity, percent.
 +MaserTempC Box temperaure, degrees C
 +MaserRH ​   Box relative humidity, percent
 +MaserBatt ​ Maser battery indicator, volts.
 +GenBatt ​   Generator battery, volts.
 +
 +Comments:
 +The command provides monitor and control of the IF PIC.
 +
 +Command parameters are in four separate sets: (1) switch, (2) diode,
 +(3) SLatt, SRatt, XLatt, XRatt, and (4) 0p5dB. ​ Each set can be
 +commanded without affecting the others, or in combination with others,
 +by leaving parameters that are not to be updated null
 +(empty). Trailing null parameters may be omitted,
 +
 +The 0.5 dB toggle inverts the state of the 0.5 dB attenuator for each
 +channel, i.e., it may increase or decrease the atenuation by 0.5 dB
 +depending on whether the initial state was an integer dB or integer
 +plus 0.5 dB, respectively. Commanding the attenuators again overrides
 +this setting.
 +
 +If any attenuator (SSLatt, SRatt, XLatt, or XRatt) hasa value
 +commanded, they must all be commanded.
