OPENing "COM1: " for a Printer May Print Random Characters (42854)
The information in this article applies to:
- Microsoft QuickBASIC Compiler for the Apple Macintosh 1.0
This article was previously published under Q42854 SUMMARY
OPENing COM1: to output to a printer may cause random characters to be
printed or overprinted. This is related to the amount of time required
for communications port handshaking. To correct the problem, you must
turn on hardware handshaking as shown in a separate article in this
KnowledgeBase -- query for IMAGEWRITER AND COM1 AND _CONTROL.
This information relates to Macintosh QuickBASIC Version 1.00 and
Macintosh BASIC Interpreter Version 3.00. Earlier versions have
hardware handshaking on by default, and the buffer overflow does not
occur.
