Input/Output Devices
The PK-88 can be used with any standard ASCII data terminal or computer
equipped with an RS-232C serial data port and a communications program or
terminal emulator. Data and control signals are exchanged between the PK-88
and the computer or terminal at standard RS-232C (CCITT V.24/V.28) levels.
Your computer and terminal program and their associated tape, disk and printer
1/0 devices provide the means to store messages received and retrieve messages
for transmission. Although highly desirable, these peripheral or 1/0 devices
are not needed for PK-88 operation.
Note
In this Operating Manual, 'computer' and 'terminal' mean the same
thing - the keyboard and monitor or printer with which you
communicate with the PK-88.

System Transmitter/Receiver Performance Requirements
Most modern radio transceivers are capable of excellent packet radio
performance. Radio switching and other delays can be compensated by parameter
value adjustments to the PK-88.
The PK-88 provides software-controlled timing variations that permit operation
with almost all HF and VHF/UHF radios in general use today.
