Marrinson) Newsgroups: comp.unix.bsd.bsdi.misc Subject: Serial Port Recommendation Date: 12 May 1995 20:46:17 -0500 Organization: WorldWide Access - Chicago Area Internet Services Lines: 15 Message-ID: <3p1319$dne@sashimi.wwa.com> NNTP-Posting-Host: sashimi.wwa.com I am considering purchasing a 28.8 modem. Currently I am using a 16550 UART with my 14.4 modem (talking to the modem at 38.4K) and getting occassional silo overflows with ppp. Since I'll probably want to run the 28.8 modem at least 56K, I'm wondering what I can do to prevent silo overflows. Should I change the FIFO trigger level of my 16550? (I'm not clear on whether you can do that.) What serial card are people out there using with high-speed modems? Looking through the documentation on the various supported cards (I'm running 2.0) I was disappointed to see that most of them topped out at 38.4K. Andrew H. Marrinson (ahm@wwa.com)
