Very good.

I have no experience with inputattach, but looking at
utils/inputattach.c from
https://sourceforge.net/projects/linuxconsole/files/latest/download
around line 1163:
switch(baud[i]) {
case -1: break;
case 2400: type[i]->speed = B2400; break;
case 4800: type[i]->speed = B4800; break;
case 9600: type[i]->speed = B9600; break;
case 19200: type[i]->speed = B19200; break;
case 38400: type[i]->speed = B38400; break;
case 115200: type[i]->speed = B115200; break;
default:
fprintf(stderr, "inputattach: invalid baud rate '%d'\n",
baud[i]);
return EXIT_FAILURE;
}
and
$ grep -A2 msc inputattach.c
{ "--mousesystems", "-msc", "3-button Mouse Systems mouse",
B1200, CS8,
SERIO_MSC, 0x00, 0x01, 1, NULL },
So, yes, you found a bug.
Add this before the "case 2400" line:
case 1200: type[i]->speed = B1200; break;
compile and test.
