- @@Server Transmit Sets
- Each transmit set is named and contains communications
- parameters that can be applied as default settings to line
- and group definitions. The information defined here
- includes items such as line speed, parity, data bits,
- and stop bits. In addition, information that controls
- network transmission such as packet size, network
- transmission timers and trigger characters is also
- specified.
-
- When you define a line or group, you can reference a
- complete set of communication and network parameters
- simply by giving the transmit set name. The parameters
- associated with a line or group are used as the default
- values for both communications and network transmission if
- a ModemShare client doesn't provide these parameters when
- requesting a connection. See the Help topic "Server
- Values For a Connection" for a description of how the
- complete set of communication and network parameters is
- selected when a connection is made.
-
- You should define a transmission set for each unique
- combination of these (communication/network) parameters
- that you want to apply to individual lines or line group
- definitions.
-
- For example, suppose that you have two physical ports on
- the ModemShare server, one with a 4800-baud modem and the
- other with a 9600-baud modem. You'll need two transmission
- sets (one reflecting a 4800-baud line speed and the other
- for the 9600-baud line). If both of the lines have the
- same speed modem and you want to supply identical values
- for both lines, only one transmission parameter set needs
- to be defined.
- @@Server Lines (Ports)
- Each physical line that is to be shared by the ModemShare
- server must be defined. This definition includes the
- hardware address of the line and the interrupt level that
- will be used to service the line. If you use standard
- computer communications (async) ports, you'll be limited
- to two lines because each needs a separate interrupt level
- to operate properly. This is true even though most current
- boards are capable of being addressed at one of four
- different addresses.
-
- Common name Address Interrupt level
-
- COM1 3F8 4
- COM2 2F8 3
- COM3 3E8 4
- COM4 2E8 3
-
- Notice that even though four different addresses are used,
- only two interrupt levels (3 and 4) are used. This means
- that, for example, you could not use COM1 and COM3
- together on the server.
-
- Optionally, you can use a multiport board which contains
- either four or eight external connections. A multiport
- board uses only one interrupt level and, because two
- interrupt levels are normally reserved for asynchronous
- ports (actually, you can use any interrupt level that is
- not in use), you can install two in each server.
-
- In any case, you must know the correct hardware address
- and interrupt level for each line (port) or the server will
- not function properly. Please consult the hardware manuals
- that came with your equipment to determine the proper
- values to specify.
- @@Server Group
- Groups perform two primary functions in the ModemShare
- server. The first is to give a name (which can then be
- used by ModemShare clients to request connections) to a
- set of lines that can supply a common service. For
- example, you define a group of all lines which are
- attached to a 4800-baud modem. Similarly, you could define
- a group of lines attached to a 9600-baud modem. Since
- almost all 9600-baud modems are capable of running at
- 4800-baud, you could include all of the 9600-baud lines in
- the 4800-baud line group. This grouping allows clients to
- request connections based on a general requirement (such
- as line speed) and increases the likelihood that a line
- will be available when requested. You can define any line
- grouping that suits your requirements based on any
- criteria that you choose.
-
- The second use of a group is to apply different default
- values to the same line or set of lines based only on the
- name used in the connection request. You could, for
- example, define a group called "DOWJONES" that contained
- the proper communications parameters (speed, parity, flow
- control, etc.) for accessing this service.
-
- A group contains one or more lines and a single line may
- belong to many groups.

-
- Note that the inbound facility is not the same as a

- the line and modem can continue to be used for outgoing
- calls. If a client allocates a line and modem, and sets

- @@Call Forward Name
- Call Forward allows you to bypass the normal
- conversation that the ModemShare server has with an
- off-network caller and automatically runs the communication
- program you selected when you ran the INHOST program. This
- permits the communication program to see a full call
- sequence since the server doesn't answer the phone.
-
- For Call Forward to be active, the following conditions

- INHOST program using the same service name that you
- specify as the Call Forward name.
- o The group must have at least one line selected as an
- inbound line (see Help topic "Server Inbound Service").
-
- If the above conditions are met, the server doesn't answer
- the phone when a ring is detected. The service name is used
- for a connection request as if the caller had typed it in
- during the standard inbound conversation. If the request
- fails, then standard inbound processing is started.
-

- as any characters might be in the transmitted data.
-
- No flow control is used when pacing is performed by a

- have a hardware address that is unique and isn't being
- used by any other device in the system. The address can be
- specified either as a decimal or hexadecimal number
- followed by the character h.
-
- The standard "COM" addresses are shown below.
-
-
- Common name Address Interrupt level
-
- COM1 3F8 4
- COM2 2F8 3
- COM3 3E8 4
- COM4 2E8 3
-
- @@Modem Presence
- Each line must specify whether or not a Hayes-compatible
- modem is attached. If you indicate that a modem is
- attached, the ModemShare server will check for the presence
- of the modem and, if no modem is attached, will reset this
- value.
-
- Modems are required for lines that either have a phone
- number associated (for automatic dialing) or are being
- used with the inbound feature.
-
- If you're using the INSYNC ModemShare inbound calling
- feature, you must indicate that the line has a modem
- attached, you may specify a setup string for the modem
- and you can choose to set the port speed to the line
- speed when an inbound call is detected. The alternative
- to matching speeds is to fix the port speed at the value
- selected in the server parameter file regardless of the
- line speed detected when an incoming call is answered.
- @@Inbound Setup String
- Used only for inbound lines, this specifies the modem
- initialization string that is to be used to condition
- the modem to accept incoming calls. Lines that you
- indicate have a modem but aren't marked as inbound lines
- are reset with the string ATZ when a connection is
- terminated.
-
- The string can be up to 32 characters long and must begin
- with the characters AT. A carriage return character is
- always appended to the string.
-
- The default setup string is ATQ0E1X1V1S0=0
-
- The default string, for most Hayes-compatible modems, will
- satisfy the ModemShare server requirements for inbound modem
- conditioning. In order for inbound service to work
- properly, your modem must be set to the following state:
-
- o Commands must be echoed (E1 in the default string)
- o Command responses must be returned (Q0)
- o Verbal command responses must be returned (V1)
- o Minimum set of command responses and trans-
- mission speed must be returned when a connection is
- made (X1)
- o Auto answer must be disabled (S0=0)
-
- In addition, you may need to set parameters to ensure:
-
- o The modem is in DTR normal mode (drops a connection
- and returns to command state when DTR is dropped)
-
- o Returns the port (not the line) speed when a
- connection is made, preceded by the characters
- CONNECT, for example: CONNECT 9600
-
- The port speed returned is used only if you choose to
- match speeds (see the description that follows). If
- you aren't matching speeds, it doesn't matter what
- speed is reported in the CONNECT string as the server
- will ignore the information.
-
- In addition to specifying an initialization string, you can
- choose to have the port speed set to the line speed when an
- inbound call is detected. The alternative to matching
- speeds is to fix the port speed at the value selected in
- the server parameter file regardless of the line speed
- detected when an incoming call is answered.
- @@Server Line Interrupt Level
- You must specify the interrupt level being used by the
- line. Care must be exercised to ensure that a single
- interrupt level isn't used by more than one board or
- the system won't operate properly. The possible
- interrupt levels (and most common uses) are shown below.
- The lower the number, the higher the priority (handled
- first) in the system.
-
- Level Standard use
-
- 0 Not available, used for timer
- 1 Not available, used for keyboard
- 2 Available, generally used for network cards and
- devices such as tape drives. If possible, you
- shouldn't run your network at a higher priority
- than your lines as the network activity could
- cause data overruns to occur in high-activity
- systems.
- 3 Available, the "standard" COM2/COM4 level
- 4 Available, the "standard" COM1/COM3 level
- 5 In a PC (8088, 8086), not available if you have a
- hard disk
- In an AT (286/386/486), available if you aren't
- using LPT2 (the second parallel port). This is a
- good choice for your network card.
- 6 If you have a floppy disk, not available
- Available for systems without a floppy disk
- 7 Available if you are not using LPT1 (the primary
- parallel port)
-
- Remember that standard "COM" boards each use an interrupt
- level and that multiport boards can share a single
- interrupt level.
