So far I've been able to make a Python script that reads a csv file with the file details and transforms it into a DOWNLOAD.BBS file. Only need to work on the date and time bit-shifting. Then try to enhance it further. Quote Link to comment Share on other sites More sharing options...

Was there any further plans to include Ymodem or Zmodem ? downloads also allow up to Ymodem-G , no further plans to include Z-modem ? the MAINT program only allows to set the modem speed up to 9600 , is this the limit of the software or would 19200 (or higher) be feasible ? And last but not least, a merry Christmas and a happy NewYear to all . Quote Link to comment Share on other sites More sharing options...

Lastic Posted February 11 Share Posted February 11 Just throwing my crazy ideas out here until I get my hands on 2 Wimodem232 Pro's (end of February) to have at least a baseline of same modem types with same settings. MegaSTe setup with the 2 standard serial ports. I have a Wimodem232 connected on Serial 1 which is detected and allows callers to connect. I have a Wimodem clone connected on Serial 2 which is detected but Michtron keeps saying there is a call detected altough I did not connect to it ? This might be due to the Wimodem clones firmware or settings hence this will become easier if I have 2 Wimodem232's. My current setup Wimodem232 fixed LAN IP , fixed port WimodemClone different fixed LAN IP, different port I was basically thinking of using a Software Loadbalancer that makes a pool of 3 IP's 1 VIP or the main LAN IP and port to which users can connect ,which is load-balanced and which is NATed to a public WAN IP with dyndns behind it for accessing it from the Internet. 2 seperate IP's and ports for both Wimodems, and let the software loadbalancer check if telnet is BUSY then switch to the other next available IP. If both are busy well I guess then I need a 3rd serial port In theory this setup would allow for 2 connected users simultanously or well that is what I'm thinking what would be working.

Techman Posted February 11 Share Posted February 11 I don’t think serial port 2 on the MegaSTe is supported. Serial ports > 1 on the Atari expected the DC Port. I’ll check the source later. Quote Link to comment Share on other sites More sharing options...

I did a few internet searches, and I can’t seen to locate any technical information on the additional serial ports (the Wiki says 3 ports?). Pretty sure the binary could be patched to handle the extra ports. My Mega4 is still boxed up, hasn’t been turned on in years. I intend to pull it out and turn it on one of these days. I did compile the source on my MacBook, and made some updates that allows it to operation over native IP on OSX, I also intend to see if I can cross compile it to a TOS executable.

The Mega STe has 2 standard Serial Ports (on the picture just beneath the power connector) and an extra one on a card ( left of the power connector) . Mine only has the 2 standard ones but a normal Mega STe would have the 2 standard serial ports + extra serial port. Currently working but I will see if I can find more relevant technical info later after work. A patched version would basically allow a standard MegaSTe to have 3 modems connected without the use of the DC Port Extender. Quote Link to comment Share on other sites More sharing options...
+DarkLord Posted February 13 Author Share Posted February 13 Well...the first serial port on the Mega STe is a bog standard ST serial port limited to 19200. The second serial port on the Mega STe is not a bog standard ST serial port. It will allow much much faster speeds, up to 57600 (IIRC). HTH's...

Techman Posted February 13 Share Posted February 13 The serial driver in MBBS is about 1,500 lines of assembler. It consists of two layers, the lower level that manages the interrupts, etc. and a higher level that the ‘C’ code calls and manages the send/receive buffers, baud rate, DTR, CTS, etc. It would be possible to work in an alternative if the technical details were know.

Are these the onboard serial ports Modem1 and Modem 2 ? Since I don't have the VME card with tthe 3rd serial port, is that also a standard one or does it allow higher speeds also ?

I don't have the VME card with the 3rd serial port either, but if I recall correctly, it's also higher speeds than just the stock 19200 (modem 1).

Serial 2 being the LAN port on a MegaSTe. I agree with your assessment of Modem 1 +2. It looks that way to me too. I'm not so sure about the LAN port though. I think it's like the Apple LocalTalk standard and has it's own, separate port on the left side of the Mega STe (from the front), not on the VME card/port. It's between the Reset button and a MIDI port. Here's a picture: Quote Link to comment Share on other sites More sharing options...

This is what I was looking for. In the past, I had used custom serial port handlers as we were providing multi-tasking layer over a single-tasking OS, once I can figure out how to build, I’ll try to make a version that makes BIOS calls for serial I/O and then someone can test it for the group. 1 Quote Link to comment Share on other sites More sharing options...

Just for my own understanding are we talking about the 3rd serial port that sits on a card on the VME BUS or the second (SCC) onboard Serial port ?
