In SCN 4139 the code printer communication code was restructured. The restructuring was successful except for printers that respond with strings longer than 10 characters. An errant line of code mistakenly informed the communication methods that it could only receive a maximum of 10 characters. The communication method was waiting for and seeing the characters in the x370 receive buffer but it would not request them since it believed it did not have enough room in its receive buffer to hold them.
