The following fields are important:
Flow ctrl: Set your IOLAN+ port flow control to Hardware.
Then set your printer to use ‘DTR Pacing’ or
‘Hardware’ or ‘Ready/Busy’ flow control. Use
the RS-232 cable pinout described below, as
this will save a print job if the printer is turned
off or the cable becomes detached. Refer to the
Cabling Guide (Appendix C).
Access: Set this field to Remote. This sets the port of the
terminal server to listen for connections coming
from the network. There will be an INETD
process running on the terminal server that does
the listening.
You can check on the status of this process by
looking at the
Netstat screen of the terminal
server’s
Statistics menu (or show net from the
CLI prompt).
Mode: Set this field to Telnet. This puts the port of the
terminal server in Telnet mode, which will ensure
that EOF is properly negotiated before closing
down the TCP/IP connection, otherwise the tail
end of a print job could be lost.
Local port: The INETD process running on the terminal
server for this port is listening for TCP/IP
connections on TCP port 10006.
The Host
If you are already familiar with ioland, all you have to do for
the above configuration is:
ioland -T <server name> 10006 <device name>
This will start ioland process and create a device in /dev. If
you are not familiar with the ioland program, read section 8,
Other Devices Setup.
