Using TERM for UNIX on HP-UX, XMODEM receives files from an EDI mailbox without a problem. However, sending files fails after a few packets with a CRC error. There are two possible issues in this case:

1. TERM maybe sending data, but not receiving acknowledgements. If you abort the TERM script and immediately connect to the UNIX device file using the Unix command “cu-l /dev/cul0p7 -m dir”, you may find that the telephone connection is still open. In this case, you may be able to continue the session manually.To resolve this, disable local flow control on the modem. The Hayes command for that is AT&K0. Please be aware each modem may have different local flow control commands. Check the documentation for specifics.
2. If you are connecting to a GEIS network, you will need to convert the UNIX-formatted file to DOS format before sending it. The GEIS network expects DOS-formatted files. You can use the HP-UX utility dos2ux to convert the file.
