This only works if your system has 65.Xr speaker 4 66support. 67.It Fl w Ar speed 68Set the sending speed in words per minute. If not specified the default 69speed of 20 WPM is used. 70.It Fl f Ar frequency 71Set the sidetone frequency to something other than the default 600 Hz. 72.It Fl d Ar device 73Similar to 74.Fl p , 75but use the RTS line of 76.Ar device 77(which must by a tty device) 78in order to emit the morse code. 79.It Fl e 80echo each character before it is sent, used together with either 81.Fl p 82or 83.Fl d . 84.El 85.Pp 86The 87.Fl w 88and 89.Fl f 90flags only work in conjunction with either the 91.Fl p 92or the 93.Fl d 94flag. 95.Pp 96Not all prosigns have corresponding characters. Use 97.Ql # 98for 99.Em AS , 100.Ql @ 101for 102.Em SK , 103.Ql * 104for 105.Em VE 106and 107.Ql % 108for 109.Em BK . 110The more common prosigns are 111.Ql = 112for 113.Em BT , 114.Ql \&( 115for 116.Em KN 117and 118.Ql + 119for 120.Em AR . 121.Pp 122Using flag 123.Fl d Ar device 124it is possible to key an external device, like a sidetone generator with 125a headset for training purposes, or even your ham radio transceiver. For 126the latter, simply connect an NPN transistor to the serial port 127.Ar device , 128emitter connected to ground, base connected through a resistor 129(few kiloohms) to RTS, collector to the key line of your transceiver 130(assuming the transceiver has a positive key supply voltage and is keyed 131by grounding the key input line). A capacitor (some nanofarads) between 132base and ground is advisable to keep stray RF away, 133and to suppress the 134minor glitch that is generated during program startup. 135.Sh FILES 136.Bl -tag -width /dev/speaker -compact 137.It Pa /dev/speaker 138speaker device file 139.El 140.Sh ENVIRONMENT 141If your 142.Ev LC_CTYPE 143locale codeset is 144.Ql KOI8-R , 145characters with the high-order bit set are interpreted as 146Cyrillic characters.
