4.5 Send_Str
z Description:
This DLL will create a th read to send a command and receive the response-result from a g eneral purpose RS-232
device. The Send_Str is a multi-task, multi-thread DLL. This DLL is very similar to Send_Cmd except that this DLL will
not
add any char to the input string.
z Syntax:
WORD Send_Str(char cPort, char szCmd[], WORD wTimeOut, WORD wSendLen, WORD wReceiveLen)
z Input Parameter:
cPort: 1=COM1, 2=COM2, 3=COM3, 4=COM4, others = invalidate
szCmd: the starting address of the original command string (terminated with 0)
wTimeOut: constant for time-out control, unit = 1ms
wSendLen: string length of send-string
wReceiveLen: string length of receive-string
z Return Value:
NoError : OK
others = Error code, refer to I7000.H
4.6 Send_Receive_Cmd
Description:
This DLL will send a command t o CB-7000 and receive the response-result from CB-7000. If the wCheckSum=1,
this DLL will automatically add the two checksum bytes to the input string a nd check the checksum status of the receive
string. This DLL will add the [0x0D] to the end of the i nput string, szCmd. The Send_Receive_Cmd is not a multi-task
DLL.
z Syntax:
WORD Send_Receive_Cmd(char cPort, char szCmd[], char szResult[], WORD wTimeOut, WORD wCheckSum,
WORD *wT)
z Input Parameter:
cPort: 1=COM1, 2=COM2, 3=COM3, 4=COM4, others = invalidate
szCmd: the starting address of the input string (terminated with 0)
szResult: the starting address of the result string
wTimeOut: constant for time-out control, unit = 1ms
wCheckSum: 0=DISABLE, 1=ENABLE
wT: time of send/receive interval, unit = 1 ms
z Return Value:
NoError : OK
others = Error code, refer to I7000.H
