3.11.8 Local Mode Commands
The 3174 converts all local mode commands and arguments into lowercase before processing. Any numeric arguments that are required must be given in decimal. IP addresses must be entered in dotted decimal form, with no imbedded spaces, and leading zeros are not necessary.
In the following explanations of the commands, arguments must be given in the order shown. We have adopted the following convention:
• A command is shown in uppercase.
• An argument, option or variable (for example, hostname) is shown in lowercase.
Parentheses
0
denote optional arguments. If you wish to specify any optional argument, you must specify all the arguments that precede it. Abbreviations for commands and parameters are allowed. If the correct input cannot bedetermined, you will receive either an "invalid" or an "ambiguous" message.
You can use "?" after any command to get help.
NAMES Command
Purpose: The NAMES command will display any host nicknames that you have customized at your 3174 (see 3.9.13, "Defining TCP/IP Nicknames" on page 43) together with its associated I P address.
Command Format: NAMES

3174 TELNET> names

Figure 39. TCP/IP Using NAMES Command
Figure 39 shows the display for the nicknames defined in 3.9.13, "Defining TCP/IP Nicknames" on page 43.
PING Command
Purpose: The PING command is used to query the availability of a remote host.
Once issued, the PING operation will continue until the 3174 has sent a specified number of packets to the remote host (if it is available). You can stop the PING operation at any time by pressing any key.
Command Format: PING (destination (count (size))) Where:
destination
count
size
Is the remote host being queried. The destination can be:
• A nickname
• An unqualified hostname, if the host is part of the same domain as the 3174 you are attached to
• A fully qualified hostname
• An IP address
If no destination is given, the IP address, if customized in question 790 for the selected station set, is used.
Is the number of packets the 3174 should send. If count=O, the 3174 will send packets until you stop the query. Possible values are 0 through 1000 (default 10).
Is the number of bytes to send in each query. Possible values are 8 through 64 (default 64).
Example Display:
3174 TELNET> ping

Figure 40. TCPIIP Using PING Command - to Default Destination
In this display, the PING command was issued, without a destination, from an L T that selected the DEC VT100 station set number 3 (see Figure 21 on page 34).
The default destination is, therefore, as customized in Question 790.

Figure 41. TCPI/P Using PING Command - with Parameters
In this display, the PING command is issued, specifying the destination host name as mvs20, data packet size 8 bytes, and two packets to be sent for the PING operation.
3174 TELNET> ping ?
Usage: ping host size count
host - destination host name or address size - size of data packet (S-64) count - number of packets (e-leee) If unspecified, size=64 and count=le.

Messages displayed for a destination that is not known.fJ
Messages displayed for a destination that is not available.OPEN Command
Purpose: The OPEN command opens a connection to a remote host.
Command Format: OPEN (destination (remote""port)) Where:
destination
remote ""port
Is a remote host to which you wish to connect. The destination can be:
• A nickname
• An unqualified hostname, if the host is part of the same domain as the 3174 you are attached to
• A fully qualified hostname
• An IP address.
If no destination is given, the IP address, if customized in question 790 for the selected station set, is used.
Is the port number of the Telnet server at the remote host, if you want a port other than the standard Telnet port 23. Possible values are 0 through 65535.
Example Display: See Figure 35 on page 49 and Figure 38 on page 51.
CLOSE Command
Purpose: The CLOSE command will end the connection with the remote host;
that is, it is used to disconnect from a remote host. Your L T will remain in Telnet local mode.
Command Format: CLOSE Example Display:
