7. Testing Unit Using the TELNET Command
TELNET is a terminal emulation protocol. TELNET enables PCs and workstations to function as dumb
terminals in sessions with hosts on internet works.
From Windows 98/Me/XP/2000/NT, use the TELNET to test the communication of TCP/IP and SMTP
Protocol manually to the Unit. This method eliminates the SMTP Server.
For better understanding, type "telnet" in the DOS Command-line to bring up the Telnet screen. Then,
click on the Terminal menu and on Preferences, check the "Local Echo" and "Block Cursor" radio dials
and click on the OK button.
Click on the Connect menu, then click on Remote System.
Enter "25" in the "Port:" field and click on Connect button.
For example,
C:\WINDOWS>telnet
telnet to ef1.labo.pcc.com[192.168.3.5]
