Parameters:

PACLEN
sets the maximum number of data bytes to be carried in each packet's "information field".
"User data" means the characters you actually type at your keyboard (or send from a stored file).
Your PK-232 automatically sends a packet when the number of characters you type for a packet

. This value is used in both Converse and Transparent Modes.
Most keyboard-to-keyboard operators use the default value of 128 bytes for routine VHF/UHF
packet services.
Experiment with different values for

NOTE:
It is not necessary that two TNCs be set to the same
