When you set the baud rate you can set also the flow mode. See the three snaps attached.Also, how can I find out if Hyperterminal is in Handshaking mode?

No, the handshake mode is "None".Originally Posted by aratti

The setting of hyperterminal may not tell you whether the modem itself needs flow control . Typically if flow control is turned off, the RTS pin is set "high".
One thing you can try is either to set no flow contol on the SIM300(if you can), or wire an output RS232 buffer to pin 7 of the serial cable and pull the input low, which should make the RTS active on the SIM300.

sim300
This is a feature of the sim300 module. If you connect it via 3 wires then you have to connect its RTS with CTS - these are pins 7 and 8 on the DB9 RS232.
