- Patch to fix Serial Link power monitor problem.
-
- I'm sorry to report that the current patch to fix the problem with
- the Serial Link recording a high current useage after the link has
- been closed has shown up an (otherwise harmless) bug in the built in
- serial driver.
-
- The effect of the bug is for an open such as IoOpen("TTY:A") to hang
- if no device is present. If the hanging program is then terminated
- with spy or Psion+Shift+K from the shell then subsequent call to open
- would forever return "Device in use error".
-
- The problem shows up when there are two PDDs for the Serial driver
- with the same name. The fix is simply to change the name of the PDD
- installed by the patch program. This we have done.
-
- This is the reason for some of the problems reported just recently on
- Cix and Compuserve. Thanks to all reports, especially to ANDYSC @
- CIX for a precise description of circumstances when things went wrong.
-
- As the patch is a permanent patch it will be necessary to soft-reset
- the S3a before applying the updated patch. The dates on the updated
- patch are both 15th November 1993. The patch program itself claims to
- be V1.01F.
-
- As a matter of interest the patch program will not apply the patch to
- a version of the OS that does'nt need it. In EPOC terms this is any
- version greater than V318F. In terms of the ROM version number this
- is any version greater than V320F.
