Re: Question about connecting from Cisco/Sparcstation


 

That did the trick. Thanks! I just had to remove the X25 TELEBAHN profile and now it works fine

I can check my Cisco config tomorrow morning, but I recall running into something similar.? Try to adjust your profile to window size of 2 (both directions) and modulo 8, or disassociate the profile entirely.

Also, Wireshark has a comprehensive dissector for XOT, so it may prove helpful in troubleshooting and comparing with what xotpad negotiates.

I configured my Cisco as per the sample?configuration on the x25 website but it seems that I'm still missing something. Looks like the error is " ?XOT Call Confirm packet, Bad value for facility, Window size is not within permitted range." I'm able to connect to 471041 just fine from xotpad

It doesn't look like the Sparcstation 1 has jumpers on the motherboard to set the serial ports to RS423... but I also have a Sparcstation 4 and a 10 so I guess I'll just use one of those instead. Thanks!

Assuming the SparcStation 1 supports RS530 differential serial.? RS530 defines the cable, and it uses EIA/RS-423 electrical signaling.

Some Sparc serial ports can be set to RS423. I think you might get lucky with the SparcStation 1; and further assuming it’s similar to the 4 or 5; they could. ?

Hello everyone,

I'd like to connect my old Sparcstation 1 to Telebahn. I've got a Cisco 1841 with a WIC-2T, can I use a?CAB-SS-530MT cable to connect the WIC-2T directly to the serial port on the Sparcstation? And then run Sunlink on the Sparc to connect to Telebahn??

Btw my dad worked for Telenet back in the 80's and when I told him about this project, he said "why would anybody want to do that?"??
