will always be displayed on the LCD screen. Host control commands, which have a special
command header (ESC), will not be displayed on the LCD. The host commands are interpreted by
the PT630 as they are received.
Block mode applications perform similar functions to character mode, except that the input
characters will not be sent to the host one character at a time. Instead the PT630 holds the data in its
internal buffer until a termination character is received. Specifying parameter linepage, lineterm, and
pageterm in the terminal control table programs the termination character. The PT630 allows at most
two termination characters.
FormCaching Operation.
When EXEC transfers control to this EPROM-resident application
program, it allows the user to create a data entry application program by simply specifying field
prompt, type, length, input method and delimiter, etc. without having to write a comprehensive
application program. FormCaching is enabled or disabled while the PT630 is in the Supervisor mode
of operation.
3.2.2.3 COM
The
COM
command activates the PT630 Kermit server. Pressing
[CMD] then [Alpha]
returns the
PT630 to the User Mode of operation. The following list shows the available Kermit commands in
the Host/PC:
Command
Description
SEND
program
Sends a file from the Host/PC to the PT630 and
stores it in the PT630's RAM disk.
GET

Gets a collected data file from the PT630 to the Host/PC disk.
REMOTE DIR
Lists PT630 RAM disk file directory.
REMOTE DEL
filename
Deletes a program or data file from the PT630 RAM disk.
BYE
Exit Kermit Mode
Before making use of the Kermit server, switch the PT630 to the Supervisor mode and set the PT630
communication parameters to match the host/PC system. See Section 3.2.3.1 Device Configuration.
