Ok - I finally got something reliably working (on a 386dx-33 at 2.1.5.) The problem was I was using an AST4port clone card in "compatibility" mode. (Compatibility was supposed to deliver interrupts correctly; bet it didn't :-) ). This was a card I bought in 1990... Anyway, when I dug up an *ancient* serial card, replaced the 8250 with a 16550 (one that I ripped off of the 4-port clone), everything worked *beautifully*! Also, when I used the AST 4-port clone card the way it was designed (not in "compatibility" mode, but with the COM_MULTIPORT driver configured properly) - things worked there just fine as well (not a single lock-up.) Thanks for all the suggestions! - Dave Rivers -
