Data Port Types

Each of the NetGuardian's 8 data ports can be configured with different functions:
TCP
Makes reach-through available at TCP ports (Telnet).
RTCP
Raw TCP (negates Telnet negotiation). The RTCP (Raw TCP Data Port) negates Telnet negotiation and
will allow all characters (including [FF]) to pass straight through from IP to serial or serial to IP.
HTCP
High speed TCP port (only 1 HTCP port is available). An HTCP, or High-speed TCP data port, which
operates in Telnet Raw mode, was left in place to allow for compatibility when importing NetGuardian G2
firmware to the NetGuardian G5. All data ports on the NetGuardian G5 are considered High Speed. If the
device that is connected to the serial port of the NetGuardian, requires a raw TCP connection, then the
port type to use is RTCP. Changing the port type to HTCP, is the same as setting it to TCP on the
NetGuardian G5. Unlike RTCP ports, the user can only assign one port as HTCP.
PTCP
Permanent TCP (during a proxy connection, the connection will never time out).
SPS8
Serial Port Switch 8 (allows eight serial devices to be connected to single port).
UDP
Makes reach-through available at UDP ports (up to 4 UDP ports available).
CHAN
Creates logical bridge to odd/even partner. The odd/even partners are pairs of 1-2, 3-4, 5-6, and 7-8.
This allows the NetGuardian to view communication traffic in either direction when inserted in the serial
communication path between two devices. This is accomplished by going "in" to the NetGuardian with
one device and "out" to the other device from the odd/even partner port. Data is passed directly from
one port to its odd/even partner without being altered in any way. This ability greatly simplifies
troubleshooting communication problems by isolating the non-communicating device.
When CHAN is selected, the NetGuardian automatically activates the odd/even partner as CHAN. Baud
rates for the odd/even pairs can be set to any available rate except for any combination of 19200 and
38400 between the two ports. Use "SPO" filter debug to analyze protocol traffic in a terminal.
CRFT
Causes the data port to have the same functionality as the front panel craft port.
CAP
Allows the user to capture debug information. The debug information is stored in the receive queue of
the NetGuardian (See section "Monitoring Data Port Activity" for more information). This is used primarily
as a troubleshooting feature.
