Hello. I use an Absolute telnet 9.12 Lite and have a problem with transmitting XModem files.
My receiver is the ARM board, connected with PC via RS232.
Transmitting is sometimes breaked due to a lot of NAK from receiver, sometimes finished, but with repeat packets.
Transmitting using HyperTerminal is always OK.
From the log it can be seen that AT sends 1st packet, then repeat it without ACK from the receiver.
Transmittion is always OK, if after Send->XModemCRC I quickly (<1sec) choose a file to transmit.
In this time receiver sends 'C' with 1sec period. So, may be AT perceives 'C' as answer on 1st packet? And because it is not a ACK, send repeat packet.
Log in attached file.
Sorry for my english.
