PREFACE
The HUNTERmicrocomputer is a self contained and
truly portable system. Its built-in operating system
contains an accurate emulation of the world-standard
CP/Moperating system and virtual floppy disk drive,
implemented in RAMmemory. Other built-in features
include a powerful BASICinterpreter, a terminal
emulation package, a flexible text editor with full-
screen facilities based on the popular Wordstar and a
comprehensive range of communications protocols.
User memoryis shared between work areas, program and
data files.

COMMUNICATIONPARAMETERS
There has been an addition to the communications parameters in order
to provide a timeout option on both receive and transmit
communications. These values can be set from 10 seconds to 1 minute
in intervals of 10 sees, Unlike the protocol timeouts, they can be
disabled by selecting 'no' in the menu.
The receive timeout is activated when the HUNTERrequests an input
from the port. If an input is not received within the specified
time, then a communications error 181 is given. The user may elect
to try again by pressing 'X' where upon the HUNTERwill wait for an
input again for the selected time and timeout again if nothing is
received,
The transmit timeout is activated when the HUNTERtries to transmit
but is prevented from doing so by the various handshake lines. If
after the specified time the HUNTERis still not able to transmit,
then a communications error '9' will occur. By pressing 'X' the
HUNTERcan be made to re-attempt the transmission.
Both transmit and receive timeouts can be trapped by use of the BASIC
'on comms goto' statement and the error number returned in location
COMERR.
