This driver was submitted by Katsutoshi Shibuya <shibuya@mxb.meshnet.or.jp>.
Configuration
-------------
The application can choose this driver by using "CONSOLEX_DRIVER_TABLE_ENTRY"
in the driver table definition, in place of "CONSOLE_DRIVER_TABLE_ENTRY".
See consolex/cTest.c for an example and consolex/README for more information.
Programmatic Usage
------------------
- You can open 9 devices; console tty00, tty01, tty02, tty03,
rtty00, rtty01, rtty02, rtty03
tty00, rtty00 and console correspond to port#1 of MVME162LX,
tty01 and rtty01 correspond to port#2, and so on.
- tty0x are "cooked" devices. They support following flags on termios
definition;
ISTRIP, INLCR, IGNCR, ICRNL, IUCLC, OLCUC, ONLCR, OCRNL, ICANON, ECHO,
CBAUD, B38400, B19200, B9600, CSIZE, CS8, CS7, PARENB, PARODD, CSTOPB,
- rtty0x are "raw" devices. They support following flags on termios
definition;
CBAUD, B38400, B19200, B9600, CSIZE, CS8, CS7, PARENB, PARODD, CSTOPB,
- The default parameter is;
B38400, CS8, ICRNL, ONLCR, ICANON, ECHO
(but all flags except B38400 and CS8 will be ignored on raw device.)
- All devices support O_NDELAY (non blocking read/write) mode operation.
(Non-blocking cooked mode output is valid, but will not work fine.)
(Non-blocking cooked mode input with ECHO flag may be blocked while sending
echoed character.)
- All devices support hardware flow control by CTS/RTS.
(There is no way to disable it. There are no supports for soft flow control.)
- The application can use tcgetattr or ioctl to obtain the parameters of the
device into struct termios.
- The application can use tcsetattr or ioctl to set the parameters of the
device within the struct temios. The action argument (2nd arg) of the
tcsetattr must be TCSANOW.
- On opening the device, the driver activate DTR line. On closing the device,
the driver deactivate DTR line.
If 2 or more device opening occures at the same time on the same port, only
the first open procedure activates DTR line, and only the last close
procedure deactivate it.
- There are no device locking mechanisms. Application can open same device
several times.
But 2 simultanious reading operation on the same port will cause unexpected
result.
Porting Notes
-------------
- This code can be used for any Zilog SCC based board.
Change the time constant parameters and SCC register base addresses.
- This code is well separated into "device depended part" and "device
independed part".
They can use device independed part for any other board. The device
independed part requires following functions;
void SCCInitialize();
Initialize hardware.
rtems_boolean SCCGetOne(int port, char *ch);
Get one character from port. If no character is in the receiver buffer,
this function returns FALSE, otherwise TRUE.
char SCCGetOneBlocked(int port);
Get one character from port. If no character is in the receiver buffer,
wait it passing the CPU to the other task.
rtems_boolean SCCSendOne(int port, char ch);
Send one character via port. If the transmitter is not ready, this function
returns FALSE, otherwise TRUE.
void SCCSendOneBlocked(int port, char ch);
Send one character via port. Wait until the transmitter is ready, passing
the CPU to the other task.
unsigned32 SCCSetAttributes(int port, struct termios *tm);
Set device attribute according to the information in the struct termios.
c_cflags parameter (baud, parity, stopbits and code size) will be checked.
On the successful completion, this function should return 0.
unsigned32 SCCGetAttributes(int port, struct termios *tm);
Get device attribute according into the struct termios.
c_cflags parameter (baud, parity, stopbits and code size) will be set.
On the successful completion, this function should return 0.
void SCCSetDTR(port);
Activate DTR line.
void SCCResetDTR(port);
Deactivate DTR line.
void SCCSetRTS(port);
Activate RTS line.
void SCCResetRTS(port);
Deactivate RTS line.
int SCCGetCTS(port);
Return non zero when CTS line is activated.
- If you don't want console port, undefine "CONSOLEPORT".
- This code does not use ESCC feature; i.e. does not read register #4/#5/#14
