4.7.2. Flow Control
This parameter sets the local handshake method for stopping output. Generally, Flow
control is not required if the connection is used to pass a blocked protocol with block
sizes <1k (ACK/NAK protocols and the like)
- No flow control: 00
- XON/XOFF flow control in both directions: 01
- Hardware handshake with RTS/CTS lines: 02
- XON/XOFF, pass characters to host: 05
4.7.3. Port Number
This setting is the source port number in TCP connections, and is the number used to
identify the channel for remote initiated connections. The port number must be unique for
every channel, and may not be set to 0 or 9999 (Range: 1- 65535). In general the port
numbers 0..1023 are reserved in UNIX systems for specific applications. It is advisable to
use numbers in the range 2000-30000 to avoid potential conflicts (although these are
unlikely).
If the
UDP Datagram mode
is selected, the port number is used as the UDP source port
number for outgoing Datagrams. Datagrams sent to the EAD 02 with this port number are
received to this channel.
4.7.4. Remote IP Address
If automatic connection mode is selected, a connection is made to this IP address and the
set remote port number. In manual connection mode, the parts of the IP address that are
not given are taken from this value.
4.7.5. Remote TCP Port
The remote TCP port number must be set to use automatic connections, and can be set to
give a default for manual connect mode. This parameter defines the port number on the
target host to which a connection is attempted.
NOTE:
To connect an ASCII terminal to a host using a EAD 02 for login purposes, use
the remote port number 23 (This is the Internet standard port number for Telnet
services).
This port number is also used as the UDP destination port number for transmitted
Datagrams, provided the EAD 02 is used in UDP mode.
