Well, I've got a few ideas for you. Right off the bat I am wondering why you are using /dev/ttyS1 instead of /dev/cua1 (which is one of the standard call out devices). As I remember, the /dev/ttySx's are normally used as call-in devices (whether or not this actually makes a difference to the system I do not know). I'm not familiar with the cu program, as I normally use the setserial program (setserial /dev/cua1 spd_vhi) to change values for the modem. I think I once ran into a problem with a PCMCIA modem being tied up continually, and also as a result causing the mouse to not respond on the laptop I was using. I came to find out that I had to explicitly tell the kernel that the IRQ for the mouse (PS/2) was not to be assigned to any requesting PCMCIA drivers/devices. After that both devices worked fine. If I get some time, I'll try to research your problem in more detail and get back to you.
