Table 1. Summary of CH2124/60 Allowed @T
®
Commands (Continued).
Notes For Table 1.
1.
Use the exact syntax as indicated in Table 1 above.
2.
Each command line has the following format:
@T
[
command
][
=data field
]
<CR><LF>
Any information listed in bold is a required portion of the command string. Brackets [] not in bold are intended to
serve as delimiters only and are not part of the required command string. All embedded spaces are ignored
except in the data field.
3.
For the case of the User Defined email message (i.e., message sent using the
@TDM1
command), the
@TM1
must be the last ISP parameter modification command executed prior to executing the
@TDM1
the command.
This means the
@TM1
command must be executed after the
@TA1
,
@TE1
,
@TS1
and
@TU1
commands.
This programming sequence is necessary because the
@TM1
command forces the iModem to compose the
entire message and store the complete message (including headers) into flash memory prior to initiating ISP
dialup. Failure to do this will cause unpredictable results.
4.
For the case of the Input Port Status email message (i.e., message sent using the
@TD
command). When the
message type selection is
@TJ0
(or
@TK8=30,
as appropriate), the
@TM1
command execution requirements
of Note 3 above DO NOT apply.
5.
Parameter must be specified as one ASCII alphanumeric character.
6.
Parameter must be specified as two alphanumeric characters. Use a leading 0, if necessary.
7.
Effective with iModem Firmware Revisions 1.262 or greater, the
@TJ0
and
@TJ1
commands have been
replaced with
K8
parameter modifiable with the
@TK8
command.
8.
Dial-up Unix Shell account access is NOT currently supported on the
iModem Network
ISP.
9. Although
the
@TK10
command allows the DTE communication speed of the CH2160 iModem devices to be
changed, the user must ensure that the DTE communication speed selected is actually supported by the DTE.
Failure to due so could inadvertently disable communication with the iModem device.
10. If the maximum number of MESSAGE ACCEPTEDs is set to a value greater than the number of auto re-dial
attempts, the iModem will auto re-dial the number of re-dial attempts specified by the auto re-dial parameter
(
K1
). Under no circumstances will auto re-dial exceed the number of re-dial attempts specified by parameter
K1
.
11. The
@TM1
command must be executed after the
@TZ
,
@TZ0
and
@TZ1
commands. This is required to
“rebuild” the email message including headers. Failure execute the
@TM1
command will cause errors in the
header creating leading to unpredictable email transmission results.
12. NOT supported during Remote Dial-up Access session.
13. If
TK5=02
and
TK1=01
, the email message will be sent using the Back Channel feature on the first dial attempt.
14. Must
set
K11=00
to allow the CH2124/60 product to answer as a remote modem. This disables the Remote
Dial-up Access feature.
