4.1.Real TTY Mode setup
To ensure clients’ use under different mainframe operation systems, GPORT provides
two fixed port modes, i.e., Real TTY
à
COM and Real TTY
à
Gvmodem
The COM mode allows clients to map the GPORT ports into expanded COM ports of
the mainframe under WINDOWS and into expanded TTY ports under SCO UNIX.
Under the COM mode, the synchronous COM parameters (e.g. baud rate, data bit,
stop bit and flow control) change completely in conjunction with the application
programs responsible for opening the ports in the mainframe, just the way the
mainframe COM port and TTY port does.
The Gvmodem mode allows clients to bind the GPORT port into a fixed virtual
terminal port
(
ttyp?
)
in
UNIX and LINUX systems
and you must set the port
parameters(e.g. baud rate, data bit, stop bit and flow control) on GPORT by yourself.
Both modes require driving control programs to be installed in the mainframe. The
programs can be obtained from the GPORT website or from the laser compact disk
attached to the product.
