Serial Port Configuration
Verify that the PK-88's serial port and data words are set up properly for
your computer. Should your monitor display garbled or incorrect characters or
'funny' graphic symbols, you can change the PK-88's serial port parity and
word length. The common parity and word length combination is seven data bits,
even parity, one stop bit.
Your computer will probably accept the PK-88's default setting, even if it
actually uses a different setting. If your computer requires eight data bits,
you may have to set parity to 'none'; otherwise text may be interpreted as
graphics or other special characters.
To set eight bits, no parity, type:
AWLEN 8
To return to seven bits, even parity, type:
AWLEN 7
You must type the command "RESTART" for the settings to take effect. One of
these combinations will satisfy most computers. You are more likely to require
a different setting if you have a 'dumb' terminal rather than a computer, or
if you have configured your computer's serial port for some special
application. If your computer needs odd parity, set PARITY to 1.
If you see framing errors, try this for shorter characters:
AWLEN 7
