1. I'd like to send imelody in an EMS message (1 message, no need for concatenation) but when I try to put the data into the UDH field, it is limited to only 40 charactes. How can I change this?
2. What are the correct values for the "Binary", "PID" and "DCS" for sending an EMS message?

1.) It sounds like you might be running an older version of NowSMS, where the web form (Send Binary Message Other.htm in the HTML subdirectory) had a size limit on the UDH field that was defined in the HTML. You could just edit the HTML to remove that size limit ... or you can update to the v5.51 version which is the current version on our web site.

2.) The binary data field can be left blank. However, some GSM modems don't like this, so if you have problems, you may have to include some text. In v5.51, you can simply type text into this field, and we will perform the appropriate conversion ... older versions did require that you perform the conversion (the easiest thing to do is to put 0020 in this field, and specify DCS=8 ... 0020 is a space character in Unicode encoding, and DCS=8 indicates that the message text is in Unicode format).

Aside from the Unicode issue mentioned above, the DCS is normally set to 0.

PID is also normally set to 0.
