Port Description

+Interestingly, this was the first bsp submitted to the RTEMS project

+communication with the author. :)

The port was done using already existing ports to the M68020 boards,
DMV152 and MVME136.

+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
