Altirra: how to get a "non-modem" serial connection?

Sun Nov 18, 2018 4:08 PM



I'm running Altirra 3.10(?) (About-Help doesn't show the exact version number, I've inferred it from Help->Changelog) on Win10 which is running in a VirtualBox environment on my Linux machine.


I'm running kermit65 on the Atari and want to test some simple data transfer over the emulated RS232 line. Along the lines of typing "abc" on the Atari and see it on the other end, and vice versa.

I'm using "Full - SIO protocal and RS232 R: handler" emulation in Altirra. The TCP port used (9000) is relayed from the VBox environment to the Linux host. I'm running netcat on Linux.


I doesn't work. Nothing I type on the Atari arrives on the Linux side. When typing something on the Linux side I'm getting something sometimes, but mixed with "BELL" notifications from kermit. (Maybe my kermit settings aren't 100% correct, this could also be part of the issue).


But now an obvious problem I've noticed: In the "Modem setup" screen in the Altirra device mananger, when I unselect (or leave it unselected initially) "Emulate Telnet Protocol", close it, an open it again, it's always selected. I don't want the telnet protocol. I appears to be impossible to disable due to this problem.


The modem emulation seems to interpret some AT commands. I don't want that. I'd like to have an unprocessed data line, like when connecting two computers with a null-modem calble.


@phaeron, would you consider to add a straight data connection from an 850 port to a TCP port?




Pole Position (two cart versions?)

Mon Nov 5, 2018 6:51 AM

Were there two different versions of the Pole Position cartridge released by Atari?




I bought a Pole Position cart in 1984 or 1985. I seem to remember that I had to press the button to accelerate. Releasing the button would brake/slow down.


On the versions from the internet I've tried tried, the controls are reversed: accelerate by default, brake with button.


Were there two versions or is my memory playing tricks on me?


My cart came in a box with the XL design, but in the size of the 400/800 cartridge boxes. Sadly, I gave my cartridge away at the end of the eighties.

Some years ago I bought a boxed version again from Ebay, but the box is smaller (like the newer XL and XE boxes), and the controls are the same

as in the images on the internet.

Hi all,


what is the latest and greatest command line tool on Linux to convert DCM disk image files to ATR?


I was using "acvt" from Jindrich Kubec in earlier times. I should still have it somewhere, but I figured I'll ask if there's something newer and still maintained.





which DOSes know about date/time?

Tue Sep 25, 2018 5:46 PM



I'm currently implementing clock_gettime/clock_settime functions for CC65.


I have a working implementation for SpartaDOS-X.


What other DOSes keep track of date/time and have a (program) interface to get/set the system time?





Looking for an Atari 800 8KB RAM module

does anybody have such a module which (s)he would sell to me?
