6-11
input can be bypassed by pressing the enter key on
the terminal which will send an empty data string to
the host (fires the OnTermData event handler).
Data might be
! U1 MCR 80 T1 T2+ CR + LF
(Refer to the Cameo manual for the exact string
sequence you need to send.
The above example sends over a 10 second request
for reading Track 1 and Track 2). There is no reply
to the host except the magstripe data.
OutputSerial
Parameters:
data
Function:
This instructs the ActiveTerminal to send data to the
terminal’s serial port. Data must be less than 232
characters in length for each call to OutputSerial. If
you are sending data to a printer attached to the
terminal, make sure to set the Protocol parameter in
the 802 RF Terminal to XON/XOFF. See the 802 RF
Terminal Manual for details.
Special Considerations:
•
After an
OutputSerial
call is successfully completed, the terminal
will return (as data) a CR (ASCII #13 Carriage Return). This will
fire the
OnTermData
event. If there is a problem with the serial
data you will see an error message at the client and in the log (if
enabled). If the data string is too long, the
OnTermIllegalCommand
event will be fired.
•
Do not call
OutputSerial
for the Terminal again until a return
code is received.
•
Do not call an Inputxxx method for the same Terminal until a
return code is received.
•
If you need to send more than 232 characters, send the first part,
wait for the acknowledge (#13) and then send the next part.
•
Calls to
OutputSerial
cannot be combined with other method calls.
