PK-232 OPERATING MANUAL COMMAND SUMMARY
Ucmd “n” [x] Default: 0
Mode: All Host: UC
Parameters:
“n” - 0 to 4 specifying a User command that may be set.
The UCMD command is similar to the UBIT command. UCMD allows seldom used
commands that take numeric arguments (rather than ON/OFF) to be set. Presently
the functions controlled by UCMD are Pactor settings that most users will never
have to change. Still they are important enough to some users or application
programs that we have included them under the umbrella command UCMD.
The following are examples of how to use the UCMD command:
UCMD 2 Returns the present value of UCMD 2.
UCMD 1 3 Sets the function controlled by UCMD I to 3.
UCMD 3 Y Returns the value of UCMD 3 to its default.
UCMD Returns the value of the last UCMD value that was accessed.
Listed below are the UCMD functions and the default value that presently has been
assigned.
UCMD 0: [x] x = 0-30, default 3.
Sets the number of correct Pactor packets in a row that must be
received before generating an automatic request to change from 100
to 200 baud.
UCMD 1: [x] x = 0-30, default 6.
Sets the number of incorrect Pactor packets in a row that must be
received before generating an automatic request to change from 200
to 100 baud.
UCMD 2: [x] x 0-9, default 2.
Sets the number of Pactor packets sent in a speed-up attempt.
UCMD 3: [x] x = 0-60, default S.
Sets the maximum number of Memory ARQ Pactor packets that are
combined to form one good packet. When this number is exceeded,
all stored packets are cleared and Memory ARQ is re-initialized.
“UCMD 3 0” disables Memory ARQ.
