Flexible Application of UCDOS Chinese Character System

/

--------------------------------------------------------------------------------
The display sub-library and display support part in the UCDOS Chinese character system cannot be cut down. The parts that can be cut down are the keyboard support part, the association part, and the printing support part. The cut-down parts are independent of each other, and various combinations of cuts will not cause system problems. The minimum configuration of the UCDOS Chinese character system occupies about 10k of main memory space.
When printing the column titles of the report and enlarging the Chinese characters, it is often found that the ESC function code found in the printer manual equipped with the hard character library cannot be used to control the printer as expected under the UCDOS Chinese character system. What is the reason?
It turns out that, like other Chinese character systems, UCDOS has replaced the interrupt vectors of the original computer's printing, display and other modules, and there are differences from the processing of the corresponding modules in the original computer's western text state. In this case, the ESC function code cannot effectively control the printer. To solve this problem, it is very simple. According to the cut-down nature of the UCDOS system mentioned above, remove the UCDOS printing driver program and keep the remaining modules. At this time, the ESC function code can be used to effectively control the printer.
The specific steps are as follows:
Run ucdos.bat
echo off
cd\ucdos
cclext16
e350
lx→(association part)
kb→(keyboard part)
(pp1→If there is pp1, remove it in ucdos.bat)
initl
Run Setupa to cut down the printing driver program.
Keep this selection and perform a warm boot.

Post a new question: I managed to cut down UCDOS7.0 and move it to A:\UCDOS... ...
Moved KNL.COM, HZK16, RD16.COM, ASC16 over, and used a hex editor to change all occurrences of C:\UCDOS in the first two to A:\UCDOS, but it still doesn't work... ...

The UCDOS pocket version seems to have only one restriction, that is, it can only run in the UCDOS directory under the root directory of the hard disk.

The following is the statement from ko20010214 on 2003-3-13 23:05:23:
The pocket version of UCDOS seems to have only one limitation, that is, it can only run in the UCDOS directory under the root directory of the hard disk.

The real pocket version does not have this problem. The pocket version with this problem is not cracked. You can find a cracked RD16.com to add, and it will run without problems when executed.

Attach rd16.com. Open the attachment The link has expired (administrator's note)

Just changing C:\UCDOS to A:\UCDOS is useless because actually both are the same thing, both under the UCDOS folder, and UCDOS only recognizes the subsequent folder, while the drive letter is the boot drive letter of UCDOS.
