Receiving Data through Com 1

[GKBray]

Hi All,

I am attempting to write a small exe in vfp to receive data from my phone system through com 1.

I have the correct parametrs for the coms communication, as provided by the engineer that installed the system. I can receive data succesfully using Hyperterm, but I just can't seem to get anything in the input buffer of the mscomm32 Activex control.

When Hyper terminal starts, it sends some characters that displays on the screen as two exclamation marls, and a left arrow icon.

I believe that the phone system is waiting for a start communications command, so my question is :-

Does anyone know if there is a standard "Start communications" command that I could send to the phone system to initiate data transfer.

Once this is done, I belive that I could recieve the data into a temp cursor, sort it into the correct format, and then Insert it into a table.

Many thanks in advance for any comments.

I don't know if there is some standart start of comunications but you can try:

#define DC3 CHR(19) && Two exclamation marls
#define ESC CHR(27) && Left arrow

thisform.MyComm32Control.Output = DC3+ESC

and see what happens
