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)
