Transmitting a DF1 Packet

Using CALL 114 (Transmit DF1 Packet) allows the user to transmit a DF1 data

packet created by the BASIC program using PRINT#, PH0# or PH1# statements.

If PRT2 is configured for full-duplex communication, the packet will be

transmitted immediately. If PRT2 is configured as a half-duplex slave, the DF1

packet will be transmitted the next time PRT2 receives an ENQuiry from a DF1

master.
In order to check if the transfer was successful, use CALL 115 (Check DF1 XMIT

Status).
Refer to BASIC CALLs Syntax (page 105) for more information about CALLs 114

and 115.
