Synopsis
Unofficial Name: GetVariableData
BCALL Address: 5092
Receives a data packet over the link port and sends either acknowledge or bad checksum packets.
Inputs
- (header+2): size of packet data
- (iMathPtr5): address to receive data
- (arcInfo): page of address to receive data (if in Flash ROM)
- iy+1Bh set up accordingly
Outputs
- None
Destroys
- All
Comments
This BCALL will throw ERR:LINK if any problems are found. It is a subroutine of GetDataPacket.
If the checksum is valid, an acknowledgement packet is sent. Otherwise, a bad checksum packet is sent and ERR:LINK is thrown.
