[SLE] 16450 UART with ISA internal modem
Hi, I just received an old computer from a friend that I am thinking of using as a firewall/gateway if I can find an ISA 10 baseT net card. I'm pretty sure there won't be a problem but I wanted to make sure. I am using an ISA internal modem that I know works with linux ( been using it for years ). My question is does the UART only matter with an extenal modem? I can't recall if that was the case. The only reason I ask is because it's a 56k and I remember reading somewhere that one had to have a 16550 UART chip for that to work but I believe that it was only for the external modems. I've been using pentium systems with this modem up to this point but now I've got screamin' 486-33. Anybody keeping up on this kind of stuff? -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/

You're asking if you care about the UART when using an internal modem, and therefore whether your internal modem will work on this older machine. Correct? I must split the answer in two. The UART matters a great deal. A 16450 UART can't reliably support speeds higher than 19.2Kbits per second. However, your internal modem has a 16550 UART on board, and therefore doesn't care in the least about the UART on your motherboard. BTW, I have a similar setup to what you're describing. It works great, mostly (my PPP script only works reliably when I have debugging on, which fills up the message log a lot faster). You may get quicker results by looking for an ISA NIC at a used-computer-parts store, rather than new. -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/

Send your pppd a SIGUSR1 once it's up and running by means of ip-up.local. A similar tweak would be desirable in ip-down as well if you have a persistent connection. -- Bernd Felsche - Innovative Reckoning Perth, Western Australia -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/
