Subject: [PATCH] Typical sequence

RX/TX will show correct answers at startup based on rig current status
This sequence is for the dummy device

Rig command: F RX
Frequency: 14500000

Rig command: F TX
Frequency: 14500000

Rig command: V VFOB

Rig command: F 16000000

Rig command: V VFOA

Rig command: S 1 VFOB

Rig command: V TX

Rig command: f
Frequency: 16000000

Rig command: S 0 VFOA

Rig command: f
Frequency: 145000000

What should this behavior be?  Return VFOA or VFOB or error?
Rig command: S 0 VFOB

Rig command: f
Frequency: 16000000
