BText text<br />
Default: empty<br />
Mode: Packet<br />
Host: BT<br />
_________________________________ Parameters: _________________________________<br />
text - Any combination of characters up to a maximum length of 120 characters.<br />
_______________________________________________________________________________<br />
BTEXT is the content of the data portion of a beacon packet. The default text<br />
is an empty string (no message). When and how packet beacons are sent is<br />
discussed in more detail under the BEACON command.<br />
Although the beacon subject is controversial in packet circles, you can use<br />
beacon texts intelligently and benefit the packet community.<br />
o Don't type your call sign in BTEXT - the normal packet header shows it.<br />
o Don't fill BTEXT with screen graphics. Use BTEXT for meaningful<br />
information.<br />
o After you've beaconed for a week or two and people know who you are, follow<br />
the practice used by more experienced packeteers: SET BEACON EVERY 0!<br />
o Use a "%," "&", "N," "NO," "NONE," or OFF as the first characters in the<br />
text to clear the BTEXT text.<br />

CALibrate<br />
Immediate Command<br />
Mode: Command<br />
Host: Not Supported<br />
_______________________________________________________________________________<br />
CALIBRATE is an immediate command that starts the AFSK transmit tone calibration.<br />
The <strong>PK</strong>-<strong>232</strong> provides a continuous on-screen display of AFSK generator tone<br />
frequencies in Hertz. The frequency is displayed approximately twice per<br />
second, with the part number of the potentiometer associated with that tone.<br />
When Calibration is checked all packet connections will be lost, and the timeof-day<br />
clock will not advance until you quit the calibration routine.<br />
Commands available in the calibration routine are:<br />
K<br />
Q<br />
H<br />
<br />
D<br />
Toggles the <strong>PK</strong>-<strong>232</strong>'s PTT and CW keying outputs between ON and OFF.<br />
Quits the calibration routine.<br />
Toggles the generator between wide (1000 Hz) and narrow (200 Hz) shift.<br />
Toggles the audio tone between "mark" (low) and "space" (high) tones.<br />
Toggles between transmitting a continuous tone or alternating the mark<br />
and space tones at a rate set by the radio baud (HBAUD) rate.<br />
