Hi, All

I start to write communication code for a 8051 variant MCU.
The code supports remote transfer data file from 8051 MCU to PC via modem. The data file is actually stay in the flash such as AM29Fxxx. when 8051 receives instruction from PC, it reads data from flash and send to UART.

We know that 8051 has a simple UART without handshaking signals, the RS232 interface I am using is MAX3235E. Since I never writing such code, I was wondering if anyone can give me following help.

(1)How fast(speed) the 8051 can reach for a stable file transfer ? 9600,19200,38400 bps or even more ?

(2)Do I need FTP protocol(such as Kermit) at PC side program ? or simply use Windows Hyperterminal to do it because it support FPT protocol.

Thanks in advance

Daniel
