Thanks to Jolan's recommendation to fiddle with umodem.c has helped. I
now have
#define UMODEMIBUFSIZE 2048
#define UMODEMOBUFSIZE 2048
It works quite well now except that almost everytime I pull out the card,
OpenBSD freezes. I guiltily admit that this may be due to me using an instable
window manager (fvwm 2.5....). I supposed I could try killing the window
manager next time.
I need to share the card between two laptops a couple times a day. It is really
a bummer to have to reboot/fsck/etc.
I also have trouble recovering from suspend/hibernate at times... might this
also be the window manager?
