IECHost: more Commodore DOS errors

Today, along with extending the “q1” command in the IECHost firmware to optionally create Commodore DOS error 21 on a full track, I also added the ominous “q3” command. As its name suggests, this new command creates DOS error 23 on a specified sector.

In the example below I tried it on t/s 22/0:

> q3 8 22 0

Trying to read t/s 22/0 results in a similar “give up scenario” as per my previous post on DOS error 21.
The error channel confirms that indeed DOS error 23 is triggered by the read attempt:

> dr 8 22 0
> ds 8
23,READ ERROR,22,00

Stay tuned!
