Update of /cvsroot/src/sys/dev/ic
In directory netbsd1:/var/slash-tmp/cvs-serv9128

Modified Files:
        com.c 
Log Message:
Fix serial console support, which was broken by the previous revision:
- In the console getc routine, block until a character becomes ready
  (no, really, we mean it).  This routine should _never_ time out.
- In the console putc routine, if the UART has trouble, do NOT proceed
  to print a diagnostic message, which would recursively invoke the
  console putc routine ad nauseum.
