I dont like to be the sort of person who, when people report problems,
fires back "it works fine here!"...but...just as a point of reference,
I have a Hayes ESP too -- it's connected to a 56k modem. I havent
had any crashes or hangs related to it, but I dont use mgetty. (I use
rungetty, a variant of mingetty, for VC's). Seeing this, I will
compile up mgetty here to see if I can replicate it.
(once in a while, communications becomes non-responsive -- but I
suspect that it's just my Zoom modem, which clams up for no apparent
reason. The port seems to be doing it's thing.)

I'm running 2.4.0-ac12 here. ESP is set to 180h, IRQ 3, DMA 3.
(I disabled my onboard serial ports). CPU is a classic Pentium.
I've been running it w/ rx_timeout=1 (the minimum usable value,
since it seems to give lower ping times)
Got this ESP off eBay -- in fact, I got it after reading Mr. Jansen's
recommendation 2 years ago in the comp.dcom.* groups (probably ISDN),
noting how flexible and tweakable the ESP drivers are. FWIW, I was
getting mountains of TCP errors before I got this card, and they all
disappeared once I installed the ESP. It's an amazing card.
