The RC2014 Single and Dual UART Modules do not have the /RTS line connected. The /DTR line is used to signal flow control.
This PR simply adds active management of the /DTR.
The current UART initialisation process already does configuration, but not active management.
The STARTZPM and STARTZCM startup alias files include commands to set the ZCPR path with "$$" as one of the parameters. The '$' characters were not escaped.
Thanks and credit to Joao Miguel Duraes for identifying this issue and Wayne Hortensius for the solution.
- UNARC updated to UNARCU11 which fixes an edge case where the user number was being incorrectly changed. See #496. Thanks and credit to Lars Nelson for this.
Rom Bank 1 has no size constraint, can increase romldr (oversize) without build issue, bank truncation
Rom bank 2 usrrom (last app) has size constraint check, shouldnt be function of app
Rom bank 2 usr rom pads to end of 32k in its Size, unnecessary as handled by "srec_cat -crop"
So
* move out the bank size protections (from user rom) into layout.inc
* ensre bank 1 has same protection as bank2.
* make user rom a realistic size ($200), padding handled by crc check
* also good to .ECHO overall sizes of banks, improve logging.
Thanks and credit to Phillip Summers for finding these and suggesting solutions.
- VGA driver initialization fixed.
- CVDU probe fixed to not rely on ready bit of CVDU
Thanks and credit to @skullandbones for pointing out multiple deficiencies in the console takeover algorithm. In this commit:
- All char units are flushed when a new RomLdr prompt is emitted.
- Intervening non-space characters will now prevent console takeover. Console takeover requires two consecutive space characters on the same character unit with no intervening non-space characters on the same unit or any intervening characters on an alternate unit.
