I'd like to install the latest release of PA-RISC Linux on it but I need to first of all be able to console into it. I am trying to use the console cable I have used with Sun boxes on this machine, however I just cannot get it to work? My terminal emulation is done via HyperTerminal on a laptopb via. COM1 I do not get any output information on my console connection. What do I need to do this? What seeting do I need on my terminal emulator? Or is there some jumper I have to set to allow this to work? Currently I use 9600 8N1, I also tried 7E1 but still no luck... Please help... Thanks...

You'll have trouble when it does come up -- we don't have proper console support yet. > I am trying to use the console cable I have used with Sun boxes on this > machine, however I just cannot get it to work?

By the way, we don't have a K220 in the hwdb yet; the closest we have is a K210. Please go to http://hwdb.parisc-linux.org/add.php3?type=machine and follow the instructions. We hope to have support for the console on the K-class later this year... -- Revolutions do not require corporate support. ^ permalink raw reply [flat|nested] 4+ messages in thread

Older Suns use a jack that's identical to what Macs use; newer Systems do have a female (!) DM25 jack which contains two serial ports: one on the "standard" pins (you only need a genderchanger and a DB25 -> DB9 converter), the other port is on the unused pins (you can buy split cables for 10 US-$ on ebay). The round jack on those Macs/SGIs/Suns do have three important pins: If you look at it, it looks like this: 1 2 3 4 5 6 7 8 (Yes, it's assymmetric). 4 and 6 are RxD and TxD, 5 is Ground. Happy MfG, JBG PS: I don't know which one of pin 4 and 6 is RxD and which one is TxD. You maybe have to try and error... -- Jan-Benedict Glaw . jbglaw@lug-owl.de . +49-172-7608481 -- New APT-Proxy written in shell script -- http://lug-owl.de/~jbglaw/software/ap2/ [-- Attachment #2: Type: application/pgp-signature, Size: 240 bytes --] ^ permalink raw reply [flat|nested] 4+ messages in thread

(1) cabeling: First of all check RS232 pinout. My E55 HP server has some non-standards, not only that the RX/TX pins are swapped, the handshake lines are completely non-standard mapped, and a simple Null-Modem cable does the wrong ! (BTW: As HP has the wrong direction, a 1:1 cable is needed, but again, the handshake lines are non-standard). So check the RS232 port on the HP box. (On my 720 and 712 I never ahd a problem, it was a standard RS232, PC-like). (2) SUN The SUN always has PC-like 25-pin connectors, but a gender-changer is needed, as SUN always has the PC-pin layout, but a female instead of male connector. Even the 8-way serial ports of SUN (old S-bus one, and new PCI one), always use the same female 25-pin connectors with PC-pinout. Special connectors as mention in the other answers is only used at Sun ICP/IPX: Mini-DIN 8pin Sun SparcStation 20 (and perhaps 10): one 25-pin female connector with two ports (you need a Y-cable). (3) Problems between PCs under BIOS/Microsoft control. As Microsoft (and PC BIOSes) is (are) a proprietary non-standard system, it also makes problems concerning the RS232 ports. Although hardware handshake is turned off, the CTS pin (pin 5 on 25pin PC connector) must be asserted. You need at mimimum a bridging cable between pin 4 and 5 (pin 7 and 8 on a DSUB-9pin). The problem does not exist on SUN and on Linux PCs. The bridge is only needed on the PC (hyperTerminal) side. (4) XON/XOFF is often used on serial console, and as far as I know, default ! So XON/XOFF should be enabnled, but again, this is my opinion. (5) Serial Console: Concerning the mail of the K220 console support. If the serial console on the K220 is not supported, you can use the new PDC Console Driver, you can find under non-standard serial drivers. It supports the PDC console driver of the firmware to use under Linux as driver `/dev/ttyB0'. In the help of this configuration option you can find the steps, how to use this. I developed this driver for my E55, as this machine is not supported, too. So I hope ypu will find some hints and solve the problem. With friendly regards Christoph P.
