Host; Hpoll - Advanced Electronic Applications PK-88 Operating Manual

PK-88 OPERATING MANUAL
⇒ Set HID ON to force the PK-88 to send an ID packet every 9½ minutes while used as a digi-
peater.
⇒ Set HID OFF to stop the PK-88 from sending any ID packets.
⇒ The HID identification packet is addressed to "ID".
⇒ Your station identification is the call sign set with the MYCALL command, with 'digipeater' ap-
pended.
For example, you've set MYCALL to WX1AAA-8 and HID is ON. The resulting automatic identifica-
tion transmission looks like:
WX1AAA-8>ID
{MYALIAS}, WX1AAA digipeater
NOTE: You cannot change the 9.5-minute automatic interval timing.
HOST ON|OFF
Parameters: ON
OFF
The HOST command permits the PK-88 to operate in the Host Mode, a 'computer-friendly' commu-
nications mode, over the RS-232 link between the PK-88 and a host computer.
In the Host Mode, the PK-88 sends data to the computer only when the computer requests data.
The data are prefaced with a special header that identifies the type of information being sent.
Turning the PK-88 on or issuing a RESTART command while in Host Mode (HOST ON) causes the
PK-88 to issue a RESTART response:
$01 $4F R T $00 $17
To cancel HOST mode, type three
BREAK character will not cancel HOST.
NOTE: Set HOST ON as the last command when preparing the PK-88 for KISS/TCP/IP oper-
ation. See Chapter 6, Host Mode and Special Applications, for more details.
HPOLL ON|OFF
Parameters: ON
OFF
The HPOLL command functions only in Host Mode and depends on specific characteristics of each
application operating in the host computer or server.
Some application programs will poll the data controller as required. In such cases, set HPOLL to
OFF.
Mnemonic: HOST
The PK-88 operates with a host computer or other special application pro-
gram.
The PK-88 operates as a normal AX.25 TNC.
[^C] characters, or the sequence
Mnemonic: HP
In Host Mode, the host computer must poll the PK-88 for all data.
The PK-88 sends data blocks to the host computer as they are formed. Data
poll is unnecessary.
