PK-900 Gateway Option Supplement
18
Two new settings of the CODE command have been added to support the European
and APLINK implementations of upper/lower case AMTOR.
CODE 7: TOR lowercase
CODE 7 applies to AMTOR operation only. It codes upper and lowercase letters
using the NULL character as a shift while in LTRS case. This protocol is used
by APLINK stations, European mailboxes, the AMT-3 and G4BMK software. The
difference between CODE 7 and CODE 2 (Cyrillic) upper/lower case is that CODE
2 uses LTRS for upper case and NULL for lowercase, while CODE 7 uses the NULL
to toggle between upper and lowercase. CODE 7 is invisible to stations using
classic AMTOR (CODE 0). However, a CODE 7 station talking to a station using
CODE 2, (AEA’s already existing upper/lower case protocol), will result in
upper/lowercase reversals or constant lower case text.
CODE 8: Extended TOR lowercase
CODE 8 also applies to AMTOR only. It includes the features of CODE 7 above,
and additionally codes new punctuation characters using NULL as an escape
while in FIGS case. Thus, CODE 8 supports all 95 printable ASCII characters
($20-7E) plus CR, LF, space and ENQ while in AMTOR operating mode, but not
BELL, backspace and TAB. At the moment, this protocol is used only on links
between mailboxes forwarding messages. It could be used with the AEA AMTOR-to-
Packet Gateway if all users had CODE 8. CODE 8 isn’t invisible to other users.
DAytime date and time Default: none
Mode: All Host: DA
Parameters:
date and time - Current date and time to set.
DAYTIME sets the data controllers real time date and time clock. Optionally,
the following types of Dallas Semiconductor “Smart Watch” chips may be used to
hold the date and time when power is turned off.
RAM—Use the DS1216C in U7 (high RAM).
ROM—Use the DS1216E or DS1216F in U3.
Setting the DAYTIME command sets the time of day into any SmartWatch present
in the system. The SmartWatch is read only on power-up, RESTART or RESET.
EXPert ON|OFF Default: OFF
Mode: All Host: EX
Parameters:
OFF Disables some of the less frequently used data controller commands in
verbose mode.
ON Enables all data controller commands in verbose mode.
