Command:
Response:
<add/IRES_'cr'
>add/IRES_tttt_xn.nE-ee'cr''lf']
Where:
tttt = FRM (FRAME) or 2047 (indicates type of error
being read).
x = < or > (data modifier to indicate that the error rate is
less than or greater than the returned value).
m.m = 1.0 to 9.9 (error rate mantissa).
ee = 1 to 99 (error rate exponent).
This command returns frame or 2047 error rate. The 'IRE_'
configuration command is used to select reading of frame
or 2047 errors.
Notes:
1. The 'x' (< or >) parameter is only returned if the
error rate has exceeded the computational
resolution of the system.
2. 'No Data' is returned if the error rate cannot be
calculated.
3. 'Sampling' is returned if not enough data is currently
available to calculate the error rate.

8P56 (8PSK 5/6)
N/A (Not Assigned)
mmmmm.mmm = Data rate in kHz.
