SP4000 Flow Computer In most applications using modem communications, the SP4000’s RS232 USAGE is first set equal to MODEM. Each SP4000 on a shared modem cable is given a unique serial device address or DEVICE ID. The BAUD RATE is commonly set to 2400, the PARITY set to NONE, and the HANSHAKING set to NONE to complete the basic setup. The remote PC’s communication settings are chosen to match these.
