[edit | edit source]HANDSHAKE portID, handshakeType
Description:
Sets the handshaking parameter for the open serial port specified by portID
(which can be either _modemPort
or _printerPort
). The handshaking parameter determines how i/o operations will be negotiated when your program subsequently writes to or reads from the specified port. handshakeType
can take any of the following values:

To determine the best handshaking format for a device, see the device's manual.
Note:
You must open the serial port (use the OPEN "C"
... statement) before executing the HANDSHAKE
statement.
Powerbooks require an initialization setting of _none
to preset the serial port properly.
