MODEM COMMUNICATION
Any authorized user may connect to and communicate with an external
modem connected to a PS-4C or PS-4E Print Server Plus. Modem
communication includes connecting to a modem from a network
workstation and issuing modem commands (e.g., dial commands). This
is referred to as "dial-out" modem communication. Modem
communication also allows a remote user to dial into a network modem
and gain access to the network through a local "host" workstation. This
is referred to as "dial-in" modem communication. Once a virtual
connection is established, the remote user may perform any operation
the local host workstation is capable of including network operations.
Print Server Plus modem communication utilizes the MSHELL.EXE and
DIAL.EXE programs. MSHELL is a memory resident program which
allows authorized users to connect to a network modem and do dial-out
communication using network communications software such as
Procomm Plus® for networks or Mirror III LAN®. MSHELL is also used
on a local "host" workstation to allow a remote user to dial-in to the
network modem and access the network through the local host
workstation using third party software such as pcANYWHERE/LAN
version 4.5. MSHELL generates various messages immediately after a
connect or disconnect string is issued in response to various conditions
as summarized in
Appendix B
.
DIAL is a program that allows users to select network modems from a
menu for dial-out operation and assign host workstation IDs for dial-in
operation. Print Server Plus modem communication also utilizes the
MOPEN.EXE and MCLOSE.EXE programs. MOPEN is used to open a
virtual connection with a network modem for dial-out applications.
MOPEN is used in dial-in applications to instruct a local host workstation
to advertise to the Print Server Plus that it can service a remote user.
MCLOSE is used to close an existing virtual connection with a network
modem for dial-out applications.
MCLOSE is used in dial-in applications
to instruct a local workstation to stop advertising that it can service a
remote user.
