Synopsis

Unofficial Name: SendReadyPacket

BCALL Address: 4F24

Sends the ready packet over the link port and receives acknowledgement.

Inputs

  • Bits 1-4 of iy+1Bh reset

Outputs

  • None

Destroys

  • All

Comments

This BCALL will throw ERR:LINK if any problems are found.

If any of bits 1-4 of iy+1Bh are set, this routine immediately returns. If the other calculator responds with a machine ID of 83h, 3,(iy+1Bh) is set.

Basically, you should assume you are talking to an 83+ and then BCALL this. If the other calculator is really a TI-83, this routine will set up iy+1Bh for you.
