Build with make & ca65.

The EasyFlash version gives you the option of loading/saving the phonebook to cart and removes Swiftlink.

ultimate version

• 2019 by alwyz

5-14-2020 v2020 beta 2

• first public beta. rewrite of pretty much everything....
• file transfers finally incorporate flow control. they never did before.
• resetvectors removed.
• re-wrote and optimized all modem drivers.
• removed a bunch of spaghetti code of my own making...

5-16-2020 v2020 beta 3

• f3 disablexfer improvements
• multi-receive disablexfer imrovements / trying to prevent crashing on multidownloads (noted on up9600)
• added punter handshake delays from ultimate version back in. baudrates faster than 2400 are definitely having problems with handshakes so its back!
• added jsr call to rsopen to baudrate changer. see if that fixes some weirdness

5-17-2020 v2020 beta 4

• found a bug on the original punter sourcecode that incorrectly references var "delay" as delay 1 on 0 off, but in truth it is 1 off 0 on, so ive set both to delay on now update... ahh fuck it, no matter what, add delays every chance we can.... i disabled every opportunity to bypass delay around pnt106.

5-18-2020 v2020 beta 5

• fixing some possible issues with multi-upload. crashes between files. enablexfer not getting turned back on at the right time?
• re-did cf1 multi-upload enable/disablexfer calls... seems good now

5-19-2020 v2020 beta 6

• merged easyflash version into this one. only added 2 blocks. easier for maintaining
• still have some room from $5000-$5100 for more code/routines if need be. And can always add more code at $5c00 before the end

5-21-2020 v2020 beta 7

• did some tweaks to autodialer. try counter now works to 99, and dial unlisted had some weird issues with that so that has been sorted as well.
• found one bug in the bottom screen display routine which has probably been there since ccgms 2017, but its good now.

5-23-2020 v2020 beta 8

• easyflash false positive with reu detect. since ef and reu cant work together, added provisions at startup to prevent easyflash mode from even looking for an reu

6-30-2020 v2021 beta 1

• doing some bugfixing. dial unlisted doesnt restore bottom of screen after dial. now it does. cosmetic fix.
• abort punter crashes stack pointer because i bypassed jump table and apparently that is neccessary so its back in the calls from dowmen and f3 routines.

9-22-2020 v2021 pre-beta2

bo zimmermans firmware (and maybe others) take issue with atdt, and prefer using atd instead for bbsing (uploads/downloads issue). hopefully this is the only issue with firmware compatibility. willing to solve this issue on the software side, though i'd prefer firmware uses a better standard. but fuck it, it's 2020 and who gives a shit anymore about standards on an 8 bit computer from the 1980s? so i added an atd/atdt menu option

12-08-2020 v2021 final

• Punter stack and Unlisted dialer bugs have been eliminated
• Support in autodialer for Zimodem and related WiFi device firmware that prefer an ATD prefix to ATDT.
