Hyperterminal substitute

Does anyone know a reliable linux substitute for hyperterminal. I have tried minicom which is ok as a terminal but has problems uploading via xmodem. One of my tasks is uploading firmare upgrades to routers and at the moment I still have to find a windows machine and run hyperterm. I do have plans to run windows via VMware for support purposes but I don't know if this will sort out my problem. ____________________________________ Giles Nunn - Network Manager Carms Schools ICT Development Centre Tel: +44 01239 710662 Fax: 710985 ____________________________________
