Hello all,

I have a question. Is it possible to communicate with a device that is connected on a com-port(rs-232)?
If so, can anyone tell me where to start looking...

Hello Menno,

Here are the functions which allow the auxiliary port to be used.

I have never used them before.

void AUX.CLOSE ()
long AUX.OPEN ()
void AUX.PRINT ( string strg(.) )

DESCRIPTION
These functions are intended for sending data to any device connected to the aux-port of the terminal.


void AUX.CLOSE()
This function closes the aux-port; after calling this function it is not longer possible to send data to the aux-port.

long AUX.OPEN()
The AUX.OPEN function opens the connection to the aux-port after which printing is possible. It returns one of the following values:

0: OK
-1: fatal error
-2: aux port busy
-3: configuration not ok
-4: not supported by this server

void AUX.PRINT( string strg(.) ) This function sends a string to the aux-port, which must be opened beforehand.


Example:
if aux.open() < 0 then
message("aux-port error")
else
aux.print("......")
....
aux.close()
endif


Good Luck

How would it be possible to READ data from a COM port? [The aux.* functions allow to write to it only.]

[The reason for the question is as follows: The application is a wire cutting machine that sends the quantity of wire out to its port, which can be connected to a com port. If I can read this quantity, I can pass it on to suitable sessions in BAAN (notably, maintain and release outbound data) to automatically decrement the inventory of wire reported consumed by the wire cutting machine.]

I too read a weight from serial port. My application does not use the aux.* commands. My process executes a PC application which reads serial port and copies data from pc to unix host and into baan variable.

I don't know how to put the link in this response but search this forum on "serial port" and select the thread "Unknown Message???". If it is useful, the code is posted.
