| Nurbol | 0:99ea9a842829 | 5 | // Description |
| Nurbol | 0:99ea9a842829 | 6 | // Program to receive ASCII format commands through a virtual COM port and |
| Nurbol | 0:99ea9a842829 | 7 | // after executing the command return some data (optional, depending on |
| Nurbol | 0:99ea9a842829 | 8 | // the command) and a status value. |
| Nurbol | 0:99ea9a842829 | 9 | // The program understands two possible commands : |
| Nurbol | 0:99ea9a842829 | 10 | // "s i j" : move servo 'i (0 to 5) to postion 'j' (0 to 90) |
| Nurbol | 0:99ea9a842829 | 11 | // "r" : read the 'i' parameter of the last "s" command |
