How do I test the serial port emulation in Altirra 2.40?


Recommended Posts

Hello there!

I've been trying to confirm serial port operation with Altirra/x64 2.40 (800 OS-B NTSC / 48K). What I'd like to do ideally is redirect the screen print output (typically using POKE'ing X,Y cursor screen location) to the serial port. Failing that a method of just sending the same print screen data to the serial port.

Before doing that of course (if possible!), I'd like to test the serial port emulation in Altirra using R: How is this configured to test the functionality with a terminal emulator such as Putty?

Altirra emulates a serial port (850, to be exact), but not to a host serial port -- instead, it also emulates a modem attached to the serial port, and in turn the "phone line" is emulated with TCP/IP. This means that to test it with PuTTY, you need to set up Altirra to accept incoming connections, connect with PuTTY over Telnet, and then "accept" the incoming call with ATA (or ATS0=1).

 

To redirect screen output, you need a replacement E: driver. I'm not aware of any off-hand that redirect over serial -- the closest is the XEP-80 E: driver, but that works over the joystick port using a custom protocol.

Thanks phaeron and 130XE for the input. I'm having some problems trying to get Altirra 2.40 to acknowledge an incoming Telnet session, this is perhaps due to my Putty configuration. Altirra just sits there with the msg, "Waiting for connection on port 9000" and Putty just terminates when I use:

 

Host Name: <my IP addr>

Port: 9000

Connection Type: Telnet

 

All other Putty settings are default.

 

I'm trying to push data from Altirra session through the simulated serial port via TCP/IP using Putty. Do I need some basic terminal code (OPEN, CLOSE etc) to go this direction?
