9fb964c828 Generalized Apple II slot setting.
In order to allow setting the Apple II slot from host computer independent code the slot setting function was renamed and dummies were added for the other host computers.

127f3031aa Map C64 F1-F8 keys to terminal keys.
The VT100 has (P)F1-(P)F4 keys. The C64 F1-F4 keys are mapped them. Additionally the C64 F5-F8 keys are mapped to the XTERM F5-F8 keys. However as we pretend to be a VT100 applications tend to ignore them.

ec848d7369 Added VT100 SCS (Select Character Set) capability.
Apple II: The MouseText chars only allow for a partial representation of the VT100 Special Graphics glyphs. Additionally the MouseText chars are not available for reversed video.

C64: The VT100 Special Graphics repurposes the ASCII(!) code points $60-$7f. And the C64 custom font used places them on the same code points. Therefore it makes sense to "tunnel" them through the usual ASCII->PETSCII->ScreenCode processing pipeline by moving them as-is to otherwise unused PETSCII code points ($80-$9f).

dabb02c638 Removed Latin-9 support.
The currently used font doesn't contain any Latin-9 glyphs so it doesn't make sense to try to process Latin-9 chars. Instead now only 7-bit ASCII chars are processed - as the original VT100 does. Setting LANG=C in the host shell should make programs aware of the fact that only 7-bit ASCII chars are to be generated.

7d50e73b5b Streamlined display character selection.
The reverse characters of the alternate char set are place in a somewhat strange arrangement in the Apple II character ROM. This is because of backward compatibility with the standard char set. Therefore it seems more efficient and hopefully easier to understand to use a table to select them.

9362e6d00c Fixed Cursor Control Key Codes.
http://vt100.net/docs/vt100-ug/table3-6.html says that ESC O A..D is to be send if Cursor Key Mode is set and http://vt100.net/docs/vt100-ug/chapter3.html says "A mode is considered set until it is reset by a reset mode (RM) control sequence.". So ESC O A..D is the default.

Beside this spec perspective sending ESC O A..D instead of ESC [ A..D makes i.e. aptitude and midnight commander work out-of-the-box.

29587a1ebe Avoid unnecessary timeout checks.
On the Apple II the timer_read function is actually a delay function. Therefore we want to avoid calling it if we're busy processing incoming data. Fortunately timer_read is only necessary to trigger a TCP keep alive message. But if we're busy processing incoming data then we for sure need no TCP keep alive. So we simply mark if we just processed incoming data and skip the timeout check.

7586cc1651 Added font for C64 VT100.
The commit e1a29ae411 was missing the font file. It sports the VT100 'special graphics and line drawing' glyphs in the chars $60-$7F. However so far the code to make use of them isn't implemented.

579b6f3334 Added VT100 test.
Re-added VT100 test that was created for KIPPERTERM development. Not very usefully as-is but a good template for any offline VT100 rendering test/debugging.

Additionally the disk images were renamed to distinguish them from the disk images created in the apps directory.

3359061ce2 Added Telnet65 app.
The file telnet.s in the 'ip65' directory for sure wasn't belonging into a library as it contained a main loop. So I introduced an 'apps' directory for actual apps coming with IP65. The file telnet.s was moved to apps, renamed telnet65.s and heavily modified.

The file c64vt100.s was made up from several files taken from CaTer (www.opppf.de/Cater) and adjusted for the new use case. The was done before for KIPPERTERM. However this time I deliberately avoided unnecessary code reformatting to allow for as easy as possible integration of potential upcoming changes in CaTer.

The file a2vt100.s was copied from c64vt100.s and adjusted to the monochrome 80 column screen of the Apple //e. Again unnecessary code changes were avoided to allow to easily merge upcoming changes from c64vt100.s.

The files atrvt100.s and vic20vt100.s are for now just dummies to allow to successfully link Telnet65. Work for an actually functional Telnet65 would start with a copy of c64vt100.s (as it was done with a2vt100.s).

ae69fe0a77 Added get_filtered_input for the ATARI.
The code is totally(!) untested but added for now to just make programs link that refer to it.

23381c5f0a Have get_key display a cursor.
On the Apple II this is already the case. The ATARI would need to be checked.

48efd846f5 Allow lower case input too.
The ][ doesn't have lower case but the //e defaults to lower case so we need to allow both upper case and lower case (and convert to lower case before DNS lookup).

e3b941008c Fixed error value.
So far the error value was set to KPR_ERROR_TIMEOUT_ON_RECEIVE on negative answer from the DNS server. Now KPR_ERROR_DNS_LOOKUP_FAILED (which was already defined) is set.

1a5bd8c7e5 Fixed ARP setup.
In general I consider the approach of a netmask length a typical case of over-optimzation - incl. the typical downside of an "unnecessary" bug. However as the optimization is already present I opted to not remove it but rather fix the bug:

So far the gateway was in usual environments only used if the target IP address differed already in the first byte from the local net IP addresses. Now the gateway is used correctly - even for i.e. the address 192.168.1.1 from the local net  192.168.0.x

344d76829a Made get_key_if_available actually work.
On the A2 get_key deletes any already pressed key. Therefore it's a bad idea(tm) to call it to retrieve the key detected in get_key_if_available. So now get_key_if_available insteads retrieves the key on its own via direct hw access. This was already done the very same way in check_for_abort_key. And apart from not working as expected the benefit of get_key displaying a cursor wasn't useful here anyway because get_key was supposed to return right away with the pressed key so the cursor wouldn't have been visible at all.

9dd014cded Replaced jsr get_key_ip65 with jsr get_key.
- The C64 variant already used get_key and I don't see a reason why the A2 has different requirements when it comes to the question when it is necessary to call ip65_process.

- On the A2 get_key does display a cursor while get_key_ip65 does not. However get_filtered_input is used to get a string of characters. This is exactly the scenario asking for a cursor.

8745021d7d Avoid trash of zero page variable.
It's not save to presume any zero page variable to stay intact after using the Ethernet drivers to perform actual network I/O. In example a necessary ARP lookup may require network I/O in not anticipated scenarios. Therefore the tftp_filename is rather to be placed in a normal variable and copied to a zero page variable just-in-time.

c4f196c71b Check for W5100 first.
Check first for a W5100 as checking for the CS8900A / LAN91C96 on similiar ports accidentally screws up a potential W5100 shared access (https://github.com/a2retrosystems/mxp/wiki/W5100-Shared-Access).

aea88482dd Added compatibility with W5100 shared access.
If the setup of socket 0 to 3 with 4+2+1+1KB is detected then the W5100 is _not_ initialized, otherwise it does set up socket 0 and 1 with 4KB each. Either way socket 0 is used - now with 4KB instead of 8KB as before.

cd0506d862 Added support for the ATARI 8-bit with Dragon Cart.
The actual ATARI-specific code is "inspired" by the IP65 variant published in http://atariage.com/forums/topic/211161-dragoncart-software/?p=2734494. The timer routines are modeled after the ones for the VIC20.

cf4d6b1fb8 Added W5100 TCP driver.
The W5100 TCP driver is intentionally very similiar to the UDP driver. It comes with its own test program (again similiar to the UDP test program) and an extension to the communication peer program to support the test program.

e451b74b07 Made use of recent changes for the web server demo.
The Apple 2 web server now uses the "combo" library and optionally uses a2_set_slot to scan all slots for the Ethernet card. Combining both with DHCP allows for complete auto configuration.
