$XMdddd:
Selects the transmitter mask. Each transmitter board is
comprised of 16 transmitters. Each transmitter can be
individually masked. Each bit in the hex value dddd
corresponds to a transmitter. For example $XM0001 would
enable only the first transmitter. Likewise $XMF00F would
enable the upper four and lower four transmitters. The
default is $XMFFFF (all on).

System x000 Sub-bottom Profiler (SBP) Commands.
$SGd: Selects the Sub Bottom Preamp Gain where d = 0 is low and
d = 1 is high. Default is 1.
$SEd: Enables (d=1) or disabled (d=0) the Sub Bottom Tx. Default
is 1.
$SWd: Selects the Sub Bottom Tx waveform where d = 0 - 15.
Default is 0.
$STd: Selects the Sub Bottom test mode where d = 0 - 6. The test
modes are as follows:
d = 0: Normal mode: RX data is sent.
d = 1: Reserved.
d = 2: Reserved.
d = 3: Generate a sawtooth waveform by holding the low
12 bits at 0xFFF, and incrementing a 12-bit
counter every sample time to drive the high
12 bits.
d = 4: Reserved.
d = 5: Send the static data pattern 1-2-3-A-B-E for every
24-bit sample.
d = 6: Redirect selected TX waveform to uplink.
Decimate the sample rate as required (8:1) and
assign to MS 8 bits of each 24-bit sample. (Low
16 bits 0x0000).
