ZULU Modem
Register Setting (Configuration Mode)
The internal registers enable various parameters to be controlled.
To set a register type ‘R#=x’ where # is the register number (1-6) and x is the value to set
For example to set the channel to channel 3 you would type the following.
R3=3<CR> (Where <CR> is carriage return or enter on the keyboard)
The modem will then return ‘OK’ or ‘Error’ if an incorrect command is entered.
One you have set the register values you must save the changes by typing S<CR>
The modem will return with ‘SAVED’
