[ES40-developers] Serial port bugfix

[Camiel V. <iam...@gm...>]

Hello everyone,

The serial port emulation had an issue where it could loose
interrupts. This has been corrected in CVS, and fixes the following
bug that David Hittner reported:

"After VMS boots using the VGA console, if you log in to the TTA0 or
TTB0 port, and it does a SET TERM /INQ, you get a message about an
invalid escape sequence, and then the echo of the character that you
are typing is 'delayed' by 4 or 5 characters, so that that you are
typing ahead blindly. If you do another SET TERM /INQ manually, the
delay increases to even more characters. REALLY odd."

Camiel.
