Werner
thanks for the link. It seems that I had the delay times wrong - I was sending
data to the modem too fast for it to follow. I increased the sleep times and it
worked perfectly. However thanks for the link because I had been looking for
some guidance as to how to use PDU formatting.

Subject: Re: [Synalist] Missing characters in SMS
Hi Petros,
I have dealt with this in the past, and resolved this by putting the modem into
PDU mode and sending / receiving messages in this way. PDU is essentially a
7-bit binary mode operation of a GSM modem.
Information on PDU can be found at:

Hi all
I use the synaser unit to send automated SMS messages from a service
application. I have tried this with SendString and ATcommand. In both cases the
received SMS message occasionally lack the first few characters.
For example:
sBlock.SendString('AT+CMGS="' + GSMaddress + '"'+ #$0D);
sleep(50);
sBlock.SendString('abcdefg 12345' + #$1A);
sleep(200);
may astually transmit 'cdefg 12345' to GSMaddress. I cannot find a patern as to
how often this occurs and how many characters get truncated.
Has anyone ever dealt with this one?
Many thanks
Petros
