Synopsis

Unofficial Name: GetSmallPacket

BCALL Address: 4EEB

Receives at most 14 bytes of a data packet over the link port and sends either acknowledge or bad checksum packets.

Inputs

  • (header+2): expected size of data packet
  • iy+1Bh set up accordingly

Outputs

  • Bytes are received to ioData

Destroys

  • All

Comments

This BCALL will throw ERR:LINK if any problems are found. It DOES NOT receive the first 4 bytes of the data packet (machine ID, command, size word). Set this up yourself.

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

BCALL 4F8A is identical to this, except it receives the bytes to ioData-1 (your guess is as good as mine).
