Installing
EasyConnection Software
Installation of the OS/2 driver software is
acheived via the OS/2 DDINSTAL command.
To install the OS/2 driver, perform the following:
Step 1.
Place the CD-ROM in the drive. The OS/2 drivers may be found in the
\OS2 directory of the CD file system.
Step 2.
Open an OS/2 Command prompt.
Step 3.
Run the OS/2 Device Driver Installation program: DDINSTAL <Enter>
Step 4.
Check that the source drive and directory (\OS2) in the Device Driver
Installation Window is correct.
Step 5.
Choose Install and select "Stallion Technologies Serial Device Driver".
Step 6.
Exit from the installation program.
DDINSTAL adds the following entry into the CONFIG.SYS
file: DEVICE=C:\OS2\EASY.SYS
For EISA, PCI and MCA adapters, no modifications
are required.
For ISA adapters, each adapter to be placed
into the machine must be specified on the "DEVICE=" entry. Using your
favourite text editor, such as "E.EXE" supplied with OS/2, modify the
"DEVICE=" entry in CONFIG.SYS.
The following example uses default settings:
Factory default PORT=2a0, and software default
MEM=D0000
DEVICE=C:\OS2\EASY.SYS /b type=EC8-64
The following example uses default settings:
Factory default PORT=2a0, software default
Oport=280, Irq=15
DEVICE=C:\OS2\EASY.SYS /b type=EC8-32
Driver Initialisation
Each time the machine is rebooted, the Stallion
OS/2 COM driver, EASY.SYS, will display messages about the adapter(s)
configured. A message like the following will be displayed:
EASY ATA V5.0.6 Copyright 1994 Stallion Technologies
Board 0:Type=EC8-32 Port=2a0 Oport=280 Irq=15: 16 ports: COM3 -> COM18
Board 1:Type=EasyIO Port=200 Irq=15: 8 ports: COM19 -> COM26
Each adapter configured will be displayed with
its configuration, number of ports, and the COM device names assigned
for the ports. If an adapter is not found or has invalid parameters
then a numbered error message will be displayed. See the Technical
Reference section for the complete list and descriptions.
Administration
Serial Port Naming Convention
As with other serial devices, Stallion ports
will be given a name of the form COM#, where # is a one to four digit
number. As each board is configured, the next group of COM# will be
assigned.
The numbering, by default, begins after other
serial ports present. If the machine currently had 2 serial ports, the
first Stallion port would be COM3. For EISA and MCA machines, adapters
will be configured in slot order, slot 1 first.
The assignment of COM# names to the ports of
a single adapter occurs in a similar manner. The first panel is assigned
the first group of COM# names assigned to the board. If an EC 8/64 had
two 8 port panels then the naming would be:
First Panel: port 0: COM1 -> port 7: COM8
Second Panel: port 0: COM9 -> port 7: COM16
Changing Port Settings
Most applications that use COM serial ports
have their own configuration method. For applications that don't, OS/2
provides a utility called MODE.EXE. Refer to OS/2's manuals or online
help for a complete description of this command. OS/2's MODE.EXE command
will however only operate on COM1 to COM9. In order to configure COM10
upwards Stallion provides a command, EMODE.EXE, that is compatible with
MODE.EXE.
Note: Do not replace your MODE.EXE
with EMODE.EXE as EMODE.EXE does not have the non-serial abilities that
MODE.EXE has.
Default COM port settings after powerup are:
1200 baud, Even parity, 7 data bits, 1 stop bit and Output Hardware
Flow control (Handshaking).
The EMODE.EXE command take arguments of the
form:
EMODE COM#:baud,parity,databits,stopbits,, [options]
| COM#: |
Port to be configured, such as COM3: |
| baud |
baud rate such as 9600, or 57600. |
| parity |
o = Odd, e = Even, n = no parity. |
| databits |
5, 6, 7, 8 bits per character transmitted |
| stopbits |
1, 1.5, 2 stop bits after each character transmitted. |
Note the empty position after stopbits. This
is required if the [options] are to be recognised. Refer to OS/2 help
on MODE.EXE, these can include flow control settings and must be separated
by comma's.
Some relevant settings are:
RTS=[OFF | ON | HS | TOG]
OCTS=[ON | OFF]
TO=[ON | OFF]
XON=[OFF | ON]
DTR=[OFF | ON | HS]
For Example:
emode com3:9600,n,8,1,, RTS=HS, OCTS=ON, XON=OFF,
DTR=ON
Driver Characteristics
1. Ports can be configured up to
230400 Baud.
2. RTS, CTS and output Software
Flow Control is implemented in the UART
firmware and thus even when the machine is heavily loaded it can still
flow control without loss of characters.
3. DCD, DSR and RTS TOGGLE flow
control are not implemented.
Note: DOS and Windows applications
can not directly access Stallion serial ports. Stallion does not provide
the required Virtual Device driver.
Driver Removal
Edit CONFIG.SYS and remove the line that loads
the Stallion Driver. The line will be of the form: DEVICE=C:\OS2\EASY.SYS
....
Delete the following files:
C:\OS2\EASY.SYS,
C:\OS2\EMODE.EXE,
C:\OS2\EDIAG.EXE,
C:\OS2\ETEST.EXE.
