| 39 | .Os |
| 40 | .Sh NAME |
| 41 | .Nm morse |
| 42 | .Nd reformat input as morse code |
| 43 | .Sh SYNOPSIS |
| 44 | .Nm |
| 45 | .Op Fl p |
| 46 | .Op Fl d Ar device |
| 47 | .Op Fl e |
| 48 | .Op Fl w Ar speed |
| 49 | .Op Fl f Ar frequency |
| 50 | .Op Fl s |
| 51 | .Op Ar string ... |
| 52 | .Sh DESCRIPTION |
| 53 | The command |
| 54 | .Nm |
| 55 | read the given input and reformat it in the form of morse code. |
| 56 | Acceptable input are command line arguments or the standard input. |
| 57 | .Pp |
| 58 | Available options: |
| 59 | .Bl -tag -width flag |
| 60 | .It Fl s |
| 61 | The |
| 62 | .Fl s |
| 63 | option produces dots and dashes rather than words. |
| 64 | .It Fl p |
| 65 | Send morse the real way. This only works if your system has |
| 66 | .Xr speaker 4 |
| 67 | support. |
| 68 | .It Fl w Ar speed |
| 69 | Set the sending speed in words per minute. If not specified the default |
| 70 | speed of 20 WPM is used. |
| 71 | .It Fl f Ar frequency |
| 72 | Set the sidetone frequency to something other than the default 600 Hz. |
| 73 | .It Fl d Ar device |
| 74 | Similar to |
| 75 | .Fl p , |
| 76 | but use the RTS line of |
| 77 | .Ar device |
| 78 | (which must by a tty device) |
| 79 | in order to emit the morse code. |
| 80 | .It Fl e |
| 81 | echo each character before it is sent, used together with either |
| 82 | .Fl p |
| 83 | or |
| 84 | .Fl d . |
| 85 | .El |
| 86 | .Pp |
| 87 | The |
| 88 | .Fl w |
| 89 | and |
| 90 | .Fl f |
| 91 | flags only work in conjunction with either the |
| 92 | .Fl p |
| 93 | or the |
| 94 | .Fl d |
| 95 | flag. |
| 96 | .Pp |
| 97 | Not all prosigns have corresponding characters. Use |
| 98 | .Ql # |
| 99 | for |
| 100 | .Em AS , |
| 101 | .Ql @ |
| 102 | for |
| 103 | .Em SK , |
| 104 | .Ql * |
| 105 | for |
| 106 | .Em VE |
| 107 | and |
| 108 | .Ql % |
| 109 | for |
| 110 | .Em BK . |
| 111 | The more common prosigns are |
| 112 | .Ql = |
| 113 | for |
| 114 | .Em BT , |
| 115 | .Ql \&( |
| 116 | for |
| 117 | .Em KN |
| 118 | and |
| 119 | .Ql + |
| 120 | for |
| 121 | .Em AR . |
| 122 | .Pp |
| 123 | Using flag |
| 124 | .Fl d Ar device |
| 125 | it is possible to key an external device, like a sidetone generator with |
| 126 | a headset for training purposes, or even your ham radio transceiver. For |
| 127 | the latter, simply connect an NPN transistor to the serial port |
| 128 | .Ar device , |
| 129 | emitter connected to ground, base connected through a resistor |
| 130 | (few kiloohms) to RTS, collector to the key line of your transceiver |
| 131 | (assuming the transceiver has a positive key supply voltage and is keyed |
| 132 | by grounding the key input line). A capacitor (some nanofarads) between |
| 133 | base and ground is advisable to keep stray RF away, |
| 134 | and to suppress the |
| 135 | minor glitch that is generated during program startup. |

| 141 | .Sh ENVIRONMENT |
| 142 | If your |
| 143 | .Ev LC_CTYPE |
| 144 | locale codeset is |
| 145 | .Ql KOI8-R , |
| 146 | characters with the high-order bit set are interpreted as |
| 147 | Cyrillic characters. If your |
| 148 | .Ev LC_CTYPE |
| 149 | locale codeset is |
| 150 | .Ql ISO8859-1 |
| 151 | compatible, |
| 152 | they are interpreted |
| 153 | as belonging to the |
| 154 | .Ql ISO-8859-1 |
| 155 | character set. |

| 160 | .Nm |
| 161 | added by |
| 162 | .An Lyndon Nerenberg (VE7TCP/VE6BBM) Aq lyndon@orthanc.com . |
| 163 | .Pp |
| 164 | Ability to key an external device added by |
| 165 | .An J\(:org Wunsch |
| 166 | (DL8DTL). |
| 167 | .Sh BUGS |
| 168 | Only understands a few European characters |
| 169 | (German and French), |
| 170 | no Asian characters, |
| 171 | and no continental landline code. |
| 172 | .Pp |
| 173 | Sends a bit slower than it should due to system overhead. Some people |
| 174 | would call this a feature. |
