where c is the channel number (range: 0–7), n1 is the first tab (range of
values for tab stops: 1–255), n2 is the second tab (all tabs must be in
ascending order), ... are subsequent tabs (maximum number of tabs:
16), nk is the last tab to set (any value less than the previous tab value
acts as a terminating character), and NUL is the terminating character.
Clear Vertical Tabs in Channel
All vertical tab stops in the specified channel are cleared. This is merely a
variant behavior of the Set Vertical Tabs in Channel function, where the
NUL acts as an early terminating character, since this function normally
clears the existing tabs before setting any new tabs.

Select Vertical Tab Channel
A specified tab channel is selected. It sets up the current tabs from that
channel. Once this function is performed, all subsequent Perform Vertical
Tab commands use the tab stops from the list retrieved from the specified
channel. At power on, the printer uses the tabs stored in channel 0.

Different character sets may be installed in the 6820 Printer. In some cases
more than one character set may be present at one time, depending on the
amount of available font memory. The 6820 Printer reserves 438K of
memory for installable fonts in FLASH memory. You can install these
character sets using NPCP or the flash configuration utility available in the
6820 Tool Kit. They can also install in flash at the time of manufacture or
service. A printer tool kit is available for installing selected font modules.

Single Byte Character Sets

SBCSs are supported for MS-DOS, PL/N, and Intermec application com-
patibility. NFT00000.MOD is the default character set (font) for compati-
bility with the 4820 Printer. NFT00437.MOD is the IBM/Microsoft
compatible character set for codepage 437.

Double-Byte Character Sets

DBCSs require two bytes to send to the printer to define the character to
print. The first byte of the character code sent to the printer is known as a
lead-in byte. The second byte of the character code is known as the trailing
byte. Different character sets have different requirements for the values of
