Synopsis

Unofficial Name: GetDataPacket

BCALL Address: 4EEE

Receives a data packet over the link port and sends either acknowledge or bad checksum packets.

Inputs

  • DE: address to receive data
  • (arcInfo): page of address to receive data (if in Flash ROM)
  • BC: expected size of data packet
  • iy+1Bh set up accordingly

Outputs

  • None

Destroys

  • All

Comments

This BCALL will throw ERR:LINK if any problems are found. It functions the same as GetSmallPacket except it receives the first 4 bytes of the packet.

If the checksum is valid, an acknowledgement packet is sent. Otherwise, a bad checksum packet is sent and ERR:LINK is thrown.
