| 60 <para> | |
| 2 | 61 For every terminal session (local, telnet, ssh or tn5250), the |
| 1 | 62 terminal emulator also makes a connection to a terminal monitor |
| 2 | 63 process, which can see cursor movement and screen contents, and can |
| 1 | 64 inject characters to send to the host. |
| 65 </para> | |
| 66 | |
| 67 <para> | |
| 68 The terminal monitor is invoked by calling an android Intent | |
| 69 named "com.five_ten_sg.connectbot.monitor.MonitorService". That | |
| 70 ensures that the monitor process is running, and should then | |
| 71 be listening on TCP port 6000 for incoming connections. The terminal | |
| 72 emulator then connects to the terminal monitor on port 6000. | |
| 73 The native android Intent and Service communication mechanisms | |
| 74 are not used. | |
| 75 </para> | |
| 76 | |
| 77 <para> | |
| 78 The messages exchanged between the terminal emulator and the | |
| 79 terminal monitor are arrays of uint16 values in network byte | |
| 80 order. Each message starts with a uint16 message byte length, | |
| 81 followed by that many bytes of data. Note that the message length | |
| 82 will always be even. The next uint16 contains the message | |
| 83 command value, and the remaining uint16 values are the arguments | |
| 84 if any for that command. | |
| 85 </para> | |
| 86 | |
| 87 <para> | |
| 88 Any arguments that are keystrokes or characters are represented | |
| 89 as 16 bit unicode. Note that the first 256 such characters are | |
| 90 identical to the ISO-8859-1 latin character set. | |
| 91 </para> | |
| 92 | |
| 93 <para> | |
| 94 INIT = 0 (TE -> Monitor). The argument is a string of uint16 | |
| 95 characters. The meaning of these characters is defined by the | |
| 96 monitor. It might be a fully qualified path name, or some other | |
| 97 data used by the monitor to drive the monitoring of this | |
| 98 connection. | |
| 99 </para> | |
| 100 | |
| 101 <para> | |
| 102 ACTIVATE = 1 (TE -> Monitor). The first argument is the | |
| 103 number of lines. The second argument is the number of columns. | |
