What modem initialization strings should be used at the central polling system?
This is never a simple answer. It depends on the modems used at the central and the modems used at the stations. Ideally a network would standardize but in practice that often does not occur. For most modems the central modems will use &f – to set a modem to the factory default e0 – to turn off the echo back of commands to the PC m0 – to turn off the annoying speaker n0 – to force the modem to immediately connect at a fixed baud rate s37 = x to set the baud rate: 9 = 9600, 8 = 4800, 6= 2400, 5 = 1200 If the modem does not support the n0s37=x commands, you can use &Nx, where 6=9600, 4=4800, 3=2400, 2=1200.
