Date: 31 Dec 1996 19:22:24 GMT Organization: Cyberport Montana. Lines: 13 Message-ID: <slrn5cipvg.kmn.myke@phluffy.cyberport.net> NNTP-Posting-Host: phluffy.cyberport.net X-Newsreader: slrn (0.9.2.1 BETA UNIX) Xref: euryale.cc.adfa.oz.au comp.unix.bsd.freebsd.misc:33379 I'm using a 2.1.0 system to send out alpha pages via HylaFax. Sometimes the modem locks up, I can get to it with Kermit but get no response back. Power-cycling the modem fixes this problem. However, other times the serial port on the machine seems to lock up. Kermit will hang when trying to set the line to /dev/cuaa1. Power-cycling the modem has no effect, and only rebooting seems to fix it. Is there anything else I can do (short of rebooting) to try and recover a hung serial port? Any idea what would cause this? - Mike myke@cyberport.net
