Colin Leroy-Mira 1093d169ad Fix BSS obliteration by mliparam during exec(). 
Using mliparam at this time could lead to corruption at the
start of the new executed program if BSS is real full and
mliparam is over $BB00.
The fix is to open the file from the loader stub instead of doing
it before the C library shutdown.

Colin Leroy-Mira 38f7daf40e Make sure not to load ACIA driver on IIgs' Z8530 
The Pascal Firmware Protocol Bytes ID are not enough to differentiate an SSC card from a IIgs serial firmware:
http://www.1000bit.it/support/manuali/apple/technotes/misc/tn.misc.08.html

Loading a2(e).ssc.ser on a IIgs succeeds, then goes to limbo when one tries to use the serial port.

Check first byte on the slot's firmware in addition to the four existing ones, as it's supposed to be $2C (BIT instruction) on an SSC card, and $EF (65C816 SEP instruction) on the IIgs' serial firmware (ROM revisions 0, 1, 3).

Colin Leroy-Mira 734541ee05 Serial: Optimize SER_GET 
There is no need to TryToSend before getting the character. We
send bytes during SER_PUT, and if interrupted during sending, we
still try to do it at the beginning of the next SER_PUT.

Colin Leroy-Mira 89af42e5cb Serial: Optimize SER_IRQ 
Apple2 and Atmos have Index in X, but can still use it for the

(when we assert flow control).
Also, standardize the free space to trigger flow control to 32
characters left (compare with RecvFreeCnt before decrement)

 2023-05-03 11:16:22 -04:00
Jeff Tranter 4d97e30b55 Source listing in bootstrap.s is incorrect. 
The OSI C1P alternative boot file format works, but the code in the
source listing does not match the ASCII-coded hex translation (which
is actually used). This is confusing to anyone trying to maintain the
code.

Also, the source code did not assemble when ASM is defined.

Also removed use of branch macros and an unnecessary "<" operator.

With these changes the source file should correctly match what
is used at run time.

Jeff Tranter 806ffe5675 Fixes and improvements to KIM-1 i/o routines. 
Tested on real KIM-1 hardware.

read.s:
- Remove commented out line.
- Remove unused check for bell character.
- Remove echo of newline (hardware always echoes entered characters).
- This fixes gets() and fgets() so they return when CR is entered.

write.s:
- Fix check for adding return after linefeed (failed to work because OUTCHR changes A)
- Remove unused check for bell character.

kim1.inc:
- Add symbol for monitor entry

crt0.s:
- Jump to KIM-1 monitor by address rather than using BRK (which relies on vector being set in RAM)

Oliver Schmidt 1daa445310 Fixed recently introduced addressing mode bug. 2022-12-22 22:09:23 +01:00
Oliver Schmidt d90c7e9853 Introduced the notion of a standard serial driver. 
There's no target with more than one serial driver (and I don't see that change anytime soon) so it's a no-brainer to apply the standard driver concept to serial drivers.

Don't empty the Receive Data Register on filling the Transmit Data Register 
The Receive Data Register and the Transmit Data Register share share a single address. Accessing that address with STA abs,X in order to fill the Transmit Data Register causes a 6502 false read which causes the Receive Data Register to be emptied.

The simplest way to work around that issue - which I chose here - is to move the base address for all ACIA accesses from page $C0 to page $BF. However, that adds an additional cycle to all read accesses. An alternative approach would be to only modify the single line `sta ACIA_DATA,x`.
