- ΓòÉΓòÉΓòÉ 1. Help for Communications Parameters ΓòÉΓòÉΓòÉ
-
- Communications Parameters help synchronize the data flow between the host
- computer system and your PC. These parameters should be set to match the
- requirements of the host.
-
-
- ΓòÉΓòÉΓòÉ 2. Baud Rate ΓòÉΓòÉΓòÉ
-
- This is the transmission speed of the communications link between your PC and
- the host computer. The standard choices are 110, 150, 300, 600, 1200, 2400,
- 4800, and 9600 bits per second. Additional choices, such as 19200, 38400, and
- 115200 may be available depending on the hardware of the personal computer.
-
-
- ΓòÉΓòÉΓòÉ 3. Data Bits, Stop Bits, Parity ΓòÉΓòÉΓòÉ
-
- Note: These three parameters are grouped in the only possible valid
- combinations. You merely need to select a set.
-
- Data Bits
- Selects the number of binary information data bits contained in each
- character. The value of this option can be either a 7 or 8. This almost
- always will be 7 if parity is used and 8 if no parity is used.
-
- Stop Bits
- Selects the number of bits which should be appended to each character to
- detect correct character framing. The value of this option can be either
- a 1 or 2. This setting is dependent on the requirements of the host
- computer system but usually is 1.
-
- Parity
- Parity is used as a method of error detection and is determined by the
- host computer. The choices for this option are None, Odd, Even, Mark,
- and Space.
-
-
- ΓòÉΓòÉΓòÉ 4. Help for Flow Control ΓòÉΓòÉΓòÉ
-
- Flow Control helps to synchronize the data flow between the host computer
- system and your PC. These parameters should be set to match the requirements
- of the host.
-
-
- ΓòÉΓòÉΓòÉ 5. Transmit Pacing ΓòÉΓòÉΓòÉ
-
- This option controls whether or not Softerm responds to pacing while
- transmitting data to the host computer. The choices for this option are
- XON/XOFF, XON/XOFF Pairs, CTS, DSR, DCD and None (the default).
-
- XON/XOFF is selected if Softerm is to perform resume and suspend operations in
- response to XON (start) and XOFF (stop) characters received from the host
- computer. Since most terminals do not have the capability to respond to XON
- and XOFF characters, this option should be set to None for most terminal
- communications to host computers.
-
- Caution: If the XON and XOFF character codes used by the host correspond to
- terminal functions other than start/stop in the terminal emulation,
- unpredictable results may occur. This option should be used only if it is a
- requirement of the host computer system.
-
- The selection of XON/XOFF Pairs is similar to XON/XOFF, except that XON and
- XOFF characters are treated as pairs. For example, if a second XON character
- is received before an XOFF, it is treated as data, rather than as a flow
- control character. In like manner, if a second XOFF is received before an XON,
- it is treated as data. (Note: This option is designed primarily for Hewlett
- Packard environments.)
-
- Clear To Send, Data Set Ready, and Data Carrier Detect simply are other
- infrequently-used methods by which transmit pacing can be controlled. As
- usual, you should use one of these methods only if required by your host
- system.
-
- If None is selected, no flow control is used. Transmissions to the host could
- overflow its receive buffer and data could become lost and/or garbled.
-
-
- ΓòÉΓòÉΓòÉ 6. Receive Pacing ΓòÉΓòÉΓòÉ
-
- This option defines the type of pacing control Softerm will use when receiving
- characters from the host computer system. The choices are None, XON/XOFF (the
- default), DTR, and RTS. The specific choice depends on the type of connection
- and the host system software. If you are unsure of the host's requirements,
- check with the System Administrator.
-
- The selection of XON/XOFF specifies the use of start (XON) and stop (XOFF)
- characters for pacing control.
-
- Selecting DTR allows the Data Terminal Ready signal from the serial interface
- to be used as a pacing control. The DTR option is appropriate only when the
- serial port is directly connected to the host computer system, rather than
- using a modem.
-
- Request To Send simply is another method by which Data Terminal Equipment can
- control pacing. As usual, you should use this method only if required by the
- host system.
-
- If None is selected, no flow control is used. Transmissions from the host
- could overflow this program's receive buffer and data could become lost or
- garbled.
-
-
- ΓòÉΓòÉΓòÉ 7. Help for System Settings ΓòÉΓòÉΓòÉ
-
- The Session profile is trying to access a communications port that is not
- available. (The port may be in use or it may not be correctly installed and
- configured.)
-
- So long as you select OK, Softerm will cycle through all the possible COM ports
- until an unused port is found or until you select Cancel.
