The Baud-rate is the transmission speed.
Here's a list of the Mazatrol controls baud rate parameter:
| T1 | Parameter A7 | 16 = 4800 | (Default at 16 which is 4800 baud) |
| T3 | Parameter A17 | 6 = 4800 | (Default at 6 which is 4800 baud) |
| T32/T+ | Parameter I1 | 2 = 4800 | (Default at 2 which is 4800 baud) |
| M2 | Fixed baudrate 4800 | ||
| M32/M+ | Parameter G1 <CMT/KASS> | 2 = 4800 | (Default at 2 which is 4800 baud) |
| 640M/MT | There's a dialog (Setting DATA I/O) |
