OPERATIONS MANUAL PPM-LX800-G
35
This section documents the usage of the WinSystems Serial Console feature
present on the PPM-LX800-G board. The serial console consists of special BIOS
code and a special terminal program used to communicate with the board. The
serial console WINCOM.EXE provides access to the Insyde CMOS setup options via
a serial port. This allows embedded system designers and technicians access to
CMOS setup on the PPM-LX800-G using only a laptop computer with a serial port.
Serial Console Reference
Introduction
WINCOM.EXE Serial Console Client
WINCOM.EXE is a DOS application that runs on a laptop or other 100% PC-compatible system.
The client is started on the DOS command line with:
wincom [port] [interrupt] [baud_rate]
(NOTE: Words in [] represent command arguments)
Argument
port
is replaced with the I/O port address of the desired COM port in hex (i.e. 3F8
for COM1 and 2F8 for COM2). This allows for the usage of nonstandard addresses for COM
ports.
Argument
interrupt
is replaced with the IRQ number assigned to the desired COM port.
Typically the values would be 4 for COM1 and 3 for COM2.
Argument
baud rate
is replaced with one of the following values which is the baud rate to use
for the connection.
1200
2400
4800
9600
19200
38400
57600
115200
NOTE
: WINCOM runs best in a pure DOS environment. It is possible to use WINCOM in a
DOS box under Windows, but there are a number of limitations in doing so and success is not
guaranteed due to differences in low-level hardware drivers. It is recommended that a DOS
boot disk be made containing
WINCOM.EXE, which can be used when access to the PPM-LX800-
G is desired.
When run in a pure DOS environment, WINCOM passes all keys and key combinations directly
to the target PPM-LX800-G. For example,
<CTRL><ALT><DEL>
will cause the PPM-LX800-G
to reboot. If WINCOM is run from a DOS box under Windows, the same key combination will
be interpreted as a Windows command. WINCOM will not receive the keystrokes and cannot
pass them to the serial console.
There are however, three keystroke combinations reserved by WINCOM and are not passed to
the target system:
<ALT><END>
Exits WINCOM.
<ALT><PgUp>
Prompts for upload filename. (Used in conjunction with SCOPY.EXE)
<ALT><PgDn>
Prompts for download filename. (Used in conjunction with SCOPY.EXE)
