Help on Uploading The 'Upload' option allows the caller to send a file to the host. The caller is shown the a menu of protocols. He/she should select the appropriate protocol by its first letter (or 'E' for Ymodem-g). If appropriate the caller is also asked for the filename. The transfer is then initiated by HOST2. The caller must then initiate the upload on THEIR side by giving their comm program an upload instruction, choosing the same protocol as they told HOST2, and giving the filename again, within 60 seconds of telling HOST2 the same information.
