Field Name |
Description |
---|---|
Com Port |
Choose a communications port from the drop-down list of ports (1–16), based on the physical connection your modem is plugged into. |
Baud Rate |
Choose the Baud rate of your modem from the drop-down list—2400, 4800, 9600, 19200, 38400, 57600, 115200, or 230400. |
Data bits |
Choose 5, 6, 7, or 8 from the drop-down list. The most common choice is 8. |
Parity |
Choose None, Odd, Even, Mark, or Space. The most common choice is None. |
Stop bits |
Choose 1, 1.5, or 2. The most common choice is 1. |
Hardware (RTS/CTS) |
Check the Hardware (RTS/CTS) check box to enable RTS (Request To Send) and CTS (Clear To Send). If you select this option, the Set RTS line high option is also automatically selected. RTS and CTS are the hardware flow control lines in a serial port connection and are part of the RS-232 standard. When RTS is “ON”, the COM port is ready to send data; when RTS is “OFF”, the COM port is not ready to send. When CTS is “ON”, the modem is ready to send data; if CTS is “OFF”, the buffer is full and the computer/terminal must wait. |
Software (XON/XOFF) |
Use the Software (XON/XOFF) check box if you are using software flow control to stop and start data transmission. |
Set DTR line high |
Check Set DTR line high to indicate the computer is ready for the modem to make a connection to another modem, according to the RS-232 standard. If DTR (Data Terminal Ready) is enabled, dropping DTR causes the modem to hang up. If DTR is disabled, you need to use software commands to make the modem hang up. |
Set RTS line high |
If you checked Hardware (RTS/CTS), the Set RTS line high option is checked and grayed out. Otherwise, you can either check this option or leave it blank. |
After you have entered all of the required information, click OK to exit the pfs/Async Setup window.
