6e035c864e Apple2 SSC: on IIgs, verify slot mode 
If the slot is not in "Your Card" mode, there's no way it is an SSC

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).

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.

89af42e5cb Serial: Optimize SER_IRQ 
Apple2 and Atmos have Index in X, but can still use it for the
best-case path as long as we reload it in the worst-case part
(when we assert flow control).
Also, standardize the free space to trigger flow control to 32
characters left (compare with RecvFreeCnt before decrement)

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.
