> would immediately
>    trap at the same breakpoint). Now GO ignores breakpoints 
> for one instruction,
>    allowing you to continue from a breakpoint.

>  - I discovered that BHBASIC requires DTR to be low or it 
> will not read/write a
>    tape image. This prevented you from loading a .PID file as 
> a basic DUMP/LOAD
>    image.
>    I have modified the virtual serial port so that DTR will 
> be asserted (LOW) if
>    either an input or output file is mounted on the device. 
> This allows you to
>    tell if a file is mounted, and also to tell the end of 
> file on input (since
>    my simulator auto-dismounts the file on EOF).

>    in the incorrect state for PANEL/TTY mode.

>  - I have decided to change the default tape image file 
> extension from ".PID" to
>    ".H8T", which stands for "H8 Tape" - this makes more sense

> 'L=' load files to ".H8L"
>    from ".PGM". [If/When I do a disk simulator, I will

>    ".H8D" for "H8 Disk"]
