Modem Setup > Modem Usage
Raw Mode
"Yes" sets the Telnet TCP port to a RAW socket. User data is treated "as is" (without interpretation) and Telnet
Command Escape capability is disabled.
"No" allows the Telnet command parser to look for escape sequences that are used to communicate control
fucntions. A common example is to support RFC-2217 Com Port Control.
Pool
Selecting yes or no determines the TCP port number that is assigned to the modem. When yes is selected the
TCP Port number assigned to the selected modem(s) is set to 6000. When a computer on the LAN opens a
Telnet connection specifiying port 6000, the MultiAccess routes the session to the first available modem
starting with the lowest tty that is set to 6000. If you want to access a specifc modem, accept the default of No.
Each selected modem will be given a specific TCP port number, starting at 7000 +.
A modem/tty port can not be set to both 6000 and 7000+ port numbers.
Note:
SSL – Secure Sockets Layer
This Pull down only applies when the usage is Modem Sharing with Authentication. SSL is a transport level
technology for authentication and data encryption. SSL negotiates a secure point-to-point socket using pre
determined Site Certificate information. Site Certificate information is used to authenticate the user and encrypt
the data. Site Certificate information is configured in the Administration menu. This option should only be used
with SSL capable Telnet clients.
Idle Timer
The Idle Timer, upon expiring, will hangup the modem and close the telnet socket. Idle time is defined as no
data flow in both directions. Any data sent or received across the socket will cause the Idle Timer to start over.
When there has been no data activity for the duration specified, the idle timer will expire.
Monitor CD
Upon the modem disconnecting, the MultiAccess will close the telnet socket.
Modem Usage
The Modem Usage table displays each modem (tty name), it's (TCP) Port number, Usage, if the TCP port is
RAW, if it's in a first available pool or not, whether SSL is enabled, and other options of Idle Times and Monitor
CD. When the modem Usage is RAS, FAX, or Custom, only Modem and Usage columns apply.
