While running my RCPM sys (DataTech 415-595-0541), I noticed XMODEM 4.2 didnt work with MODEM7 so I had to upgrade to XMODEM 5.xx ... Today, was trying to transfer a file from from my H89 to my TRS-80 and it didnt work..the TRS-80 (MODEM2) and the H89 (MODEM731) kept bombing out with TIMEOUT and 15H RCVD NOT ACK. However,my MODEM2 and MODEM7 will talk to XMODEMs on others and talk to MBOOT3 on my computers. So, I had to use MBOOT on trs-80 instead of MODEM2 to receive the file from H89 and use MBOOT on H89 instead of MODEM7 to receive from TRS-80. Really confusing...what happened to protocol standard in MODEM7xx ?? Thank you very much, Edward Huang
