Recording medium recording program causing computer to perform data transfer

A recording medium recording a data transfer program causing a computer to execute a data transfer method comprising the steps of:

• detecting that data is sent from a sender source to said computer by a first transmission method;
• and
• reporting to said sender source by a second transmission method replacing said first transmission method when it is determined that said computer cannot process said data sent by said first transmission method appropriately.

An information processing apparatus, comprising:

• a sending portion sending data to a receiving apparatus by a first communication method;
• and
• a receiving portion receiving from said receiving apparatus information about a usable communication method in said receiving apparatus when said receiving apparatus cannot normally receive said data by said first communication method.

An information processing apparatus, comprising:

• a communication portion communicable by a first communication method and a second communication method;
• and
• a control portion controlling said communication portion such that said communication portion sends information about a communication method of said information processing apparatus to a sender source by said second communication method when it is determined that said information processing apparatus cannot normally perform a reception process on data sent from said sender source by said first communication method.
