Dynamic C function reference

• int Dxmodem_scbdown( char *buffer, int count )
Sends (downloads) count 128-byte blocks in buffer using the
XMODEM protocol.
RETURN VALUE:
0 timed-out (no transfer).
1 successful transfer.
2 transfer canceled by receiver.
• int Dxmodem_scbup( unsigned long address,
int *pages, int dest, int(*parser)() )
Receives (uploads) a file using the XMODEM protocol.
PARAMETERS:
address is the physical address in RAM where the received data are
to be stored. If the receive buffer is allocated by xdata, then the name
of the array may be used for the address argument. If, however, the
data area is allocated using “normal” C, you must first convert the
logical address of the buffer to a physical address using the library
function phy_adr.
pages is the number of 4K blocks of data that have been transferred.
dest If 0, the upload is intended for the master in an RS-485 masterslave
network. If dest is nonzero, the upload is intended for the
designated slave (1–255).
parser is the function that handles parsing of the uploaded data.
RETURN VALUE:
0 timed-out (no transfer).
1 successful transfer.
2 transfer canceled by sender side.
SERIAL.LIB
These are serial driver functions.
• void ser_init_z1( char mode, char baud )
Initializes the driver for Z180 serial port 1. To use this driver, you must
use z1_ser_int as the interrupt handler for Z180 port 1. This
function uses circular receive and transmit buffers, which are allocated by
the programmer. This function tells the software what the setup is.
PARAMETERS:
mode selects the operation mode as follows.
bit 0 0 = 1 stop bit
1 = 2 stop bits
bit 1 0 = no parity
1 = with parity
