4.3 Remote TTY for Unix Systems
Remote TTY functionality makes it possible for Unix based systems (SCO Unix
of AIX) to read or write data on serial port 1 and/or serial port 2 of the SpotLine
M110 Terminal. You may also write data to the parallel port. This is
accomplished by means of using pseudo-tty’s within Unix.
SpotLine supplies a program for SCO Unix systems and AIX versions 3.2, 4.1
and 4.2 which interfaces with a serial or parallel port on the SpotLine terminal.
This program provides the “master” side of the pseudo tty connection and runs
as a background process. With this program running, your application can open
the “slave” side of the pseudo-tty to read and write data.
You must do the following to properly configure the Remote tty function on the
SpotLine terminal:
Go to the Setup Menu of the SpotLine M110 Terminal
Go to Port Configuration; in the Type field select Rtty.
Set the line characteristics to match those of the peripheral you intend to use.
(Note: Host and TERM are not used)
Save and Exit
To use the Parallel Port
Go to the setup Menu of the SpotLine M110 Terminal.
Go to Network Configuration and activate the Print Server, then select
Rtty/Parallel in the Protocol field
(Note: Default Queue Name and Printer fields are not used.)
Save and Exit
To set up the Unix software:
The daemon software ‘rttyd’ is available on a tar format diskette or downloadable
from our web site (www.SpotLine.com).
