bridge/gateway between RS232 and CAN bus. Uses ASCII encapsulation, compatible with the Socket-CAN SLCAN API, and adapters such as LAWICEL and VScom USB-CAN.
Socket-CAN, in particular the SLCAN API. http://developer.berlios.de/projects/socketcan/ also, the LAWICEL CAN-USB and Easylink adapter manuals.

can_check_uart_rx(volatile byte out device, byte in ch)
this routine is used to process incoming characters from the UART. the data stream is line-oriented ASCII, with a CR(13) terminator. sometimes the data is a command, which may need a reply back out the UART. But most of the time, the data is encapsulated CAN messages which need to be sent out the CANbus. device: uart data device, e.g. serial_hw_data ch: received ASCII char from UART

can_open_cmd(volatile byte out device, byte in ascii_buf[32]) return bit
these commands are only valid while the bridge is 'open' this routine is primarily for internal use.
can_closed_cmd(volatile byte out device, byte in ascii_buf[32]) return bit
these commands are only valid while the bridge is 'closed' this routine is primarily for internal use.
can_check_can_rx(volatile byte out device, dword in out can_id, byte in out can_data[8], byte in out data_len) return bit
this routine encapsulates incoming CANbus messages, and sends the resulting ASCII out to the UART. a copy of the CANbus message is also returned to the caller. device: uart device, e.g. serial_hw_data
can_modeless_cmd(volatile byte out device, byte in ascii_buf[32]) return bit
these commands are always available this routine is primarily for internal use.
