Description The SDLC maximum frame length refers to the bytes of the largest packet that can be
received and sent, excluding the parity bit and the start/stop bit.
The maximum receivable frame length of some PU2.0 devices is of 265 bytes, and
that of IBM AS/400 is generally of 521 bytes. Usually we need to configure it the
same value as the connected SDLC device.
