No that shouldn't be the problem.  Modems don't withold the plus sign
in order to wait for further ones.  What if another one isn't coming?

Instead, the modem immediately transmits the plus sign to the other
modem.  It takes no special action until it sees that you have paused,
sent three plus signs, and paused again.  At the moment you're sending
the plus sign, you haven't satisfied the requirement for a second pause
so the modem transmits the data immediately.  You can configure the
character the modem watches for with the S2 register, and the amount
of pause time required with the S12 register.
