The fs-based control of the SML01 over the GPIB bus has been implemented.
The created functions are:

• smlclear: reset the device.
• smlstat: report on the current frequency, power level, and rf on/off status.
• smlfreq: set a frequency (in MHz).
• smlpow: set a power level (in dBm).
• smlrf: turn the output on or off.

To clear the device, then set it to 1.0387GHz, -12dBm, with the RF on, this would look like:

smlclear
smlfreq=1038.7
smlpow=-12
smlrf=on
smlstat

With the fs output:
