Sends the ready packet over the link port and receives acknowledgement.
- Bits 1-4 of iy+1Bh reset
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.
