AST-5251/11 FUNCTIONAL ISSUES
|
||
|
||
|
||
AST Data Comm Product Marketing has reviewed all aspects of the following
|
||
functional issues relating to the 5251/11 product (part number 500222-XXX).
|
||
They have made the determination that these issues will not be resolved for
|
||
this product.
|
||
|
||
These issues are as follows:
|
||
|
||
- The user is attempting to use virtual print, to print a DisplayWrite 4
|
||
document. When trying to print to a 5219 printer, bold character codes
|
||
are being interpreted as blank spaces. (PR#A00147)
|
||
|
||
- User has 5251/11 cards in IBM XT's and XT clones. User has found that
|
||
after signing on the System 38, the systems with these cards will
|
||
randomly lock up. Removing the hard disk and controller seems to
|
||
resolve the problem. (PR#A00154)
|
||
|
||
- User has a VGA display adapter installed in conjunction with the 5251/11
|
||
card. During a cold boot of the system, the 5251/11 KERNEL program
|
||
fails to load, with an error code "5". However, during a warm boot
|
||
KERNEL successfully loads. (PR#A00181)
|
||
|
||
- The use of the Hewlett Packard LaserJet II is not fully supported with
|
||
the 5251/11 software. This means that the LaserJet II cannot be used to
|
||
emulate all functions of a true IBM System 3X printer when attached to a
|
||
PC running the AST emulation program. (PR#A00188)
|
||
|
||
- The 5251/11 adapter does not operate in a Magitronics 12MHz AT clone.
|
||
When emulation software is executed, only a blank sign-on screen
|
||
appears. The "SA" is not highlighted in the status area, and the cursor
|
||
remains in the upper left-hand corner. (PR#A00185)
|
||
|
||
- 5251/11 does not support Epson LQ850 and LQ1050 printers because
|
||
Vertical Motion Index units of n/60 are not recognized by the emulation
|
||
software. (PR#A00192)
|
||
|
||
- Under 5251/11 emulation, a Hewlett Packard LaserJet II printer is
|
||
configured as an IBM 5224 Model 1 printer. When printing any system 36
|
||
application, one or more blank pages (depending on the application) are
|
||
ejected after every form feed, which is not normal operation for this
|
||
type of printer. (PR#A00171 and PR#A00196)
|
||
|
||
- The 5251/11 emulation is installed in an "AT" type system which has
|
||
Award 3.03 BIOS. When loading the emulation software, an error code "2"
|
||
or "3" is generated, and software cannot be executed. (PR#A00189)
|
||
|
||
- Displaywrite/36 documents do not print correctly through 5251/11
|
||
emulation. The PC printer emulating a host printer does not recognize
|
||
the right margins of the Displaywrite/36 document. Also, when printing
|
||
a legal (8.5 by 14 inch) document, the PC printer does a form feed at 11
|
||
inches. (PR#A00150)
|
||
|
||
- The "End" (number 122) key on a 122-key keyboard will not remap to
|
||
another function in "shifted" or "caps lock" mode. The same key can be
|
||
remapped to another function in "lower case" mode. (PR#A00194)
