Notes:
1. This field is for switched lines only. Type a 0 for nonswitched lines.
2. Choose 1 if the modem will not answer an incoming call if DTR is already
active from the 3708.
Receive Data Threshold
Send Answertone
[00000 - 65535] optional
Type the receive data threshold count that, when exceeded, is sent unsolicited to the
host. Type
00000
to disable this function.
Note: This count is sent in the NPDA NMVT vector when the threshold is
exceeded or when the session ends abnormally.
[1,0]
I-The modem does not provide an answertone. The 3708 sends an answertone
for 3 seconds.
0- The modem provides an answertone.
Note: This field is for switched lines only. Type a 0 for nonswitched lines.
Receive Error Threshold
[00000 - 65535] optional
Type the receive error threshold count that, when exceeded, is sent unsolicited to the
host. Type
00000
to disable this function.
Note: This count is sent in the NPDA NMVT vector when the threshold is
exceeded or when the session ends abnormally.
Delay after Form Feed
For LV type 1 SCS, LV type 3, and protocol enveloping, the number of DEL
(X' 7F ') characters that are sent after a form feed (FF) character is the number that
is defined by the form feed delay during configuration. This number is also used
after a vertical tab (VT) character in protocol
envelop~ng.
[000 - 255]
Type the number of DEL (X '7F') characters that the 3708 is to transmit to the
device after sending a form feed to allow time for the print element to move to a
new position. Type
000
if you are using a buffered printer.
Delay after Carriage Return
For protocol conversion, the carriage return delay for LV type 1 SCS and LV type 3
print operations is calculated using the ratio of the position of the print element to
the platen length that is defined during configuration. This ratio is multiplied by the
carriage return delay to obtain the number of DEL (X '7F') characters that are sent
to the printer after a carriage return (CR) character.
In protocol enveloping, after a carriage return (CR) or horizontal tab (HT), the
number of DEL characters sent is the number that is defined in the carriage return
delay; no calculations are performed.
